Preliminary experience with dexmedetomidine in neonatal anesthesia
p. 17
Özcengiz Dilek, Günes Yasemin, Mustafa ATCIPMID :21804699Background: In paediatric patients dexmedetomidine has been reported to be effective in various clinical settings including provision of sedation during mechanical ventilation, prevention of emergence delirium after general anaesthesia, sedation during non invasive radiological procedures. However very few data of its use in newborn is available.
Patients & Methods: Sixteen new born patients of age 2-28 days were studied. Anaesthesia was induced with 1 mgkg -1 ketamine intravenously. Dexmedetomicline 1 μgkg -1 was infused within ten minutres. Maintenance infusion was started as 0.5-0.8 μg kg -1 h -1 until the end of surgery ortrcheel intubation was done all patients were mechanical ventelated with O2 +H2 O safberane 0.1-0.2%. Non invasive systolic & chastake blood pressure, heart rate, SPO2 , DETCO2 , inhated & end trial sevophrame conc and body temperature were monitored.
Results: No significant difference was observed in the measured values of haemodynamic parameter at different intervals and the base line values. No patient had hypotension bradycardia hypertension hypoxia or respiratory depression. Patients had mild hypothermia during post-operative period.
Conclusion: Dexmedetomidine 1 μgkg -1 followed by maintenance dose of 0.5 μg kg -1 h -1 as an adjacent to sevoflurane anaesthesia in new born undergoing laparatomy provides haemodynamic stability during heightened surgical stimulate.

Comparison of bupivacaine alone and in combination with fentanyl or pethidine for bilateral infraorbital nerve block for postoperative analgesia in paediatric patients for cleft lip repair: A prospective randomized double blind study
p. 23
Rajesh S Mane, CS Sanikop, Vithal K Dhulkhed, Tuhina GuptaPMID :21804700Background: Cleft lip repair is one of the common surgeries performed in India and the usual method used for post operative analgesia is perioperative opioids and NSAIDs. There has been an increase in use of regional techniques and Opioids are the common adjuvants but their efficacy and safety have not been studied extensively in children.
Patients & Methods: A prospective, randomized, double blind study was done to compare the efficacy, duration and safety of intraoral infraorbital nerve block on post operative pain relief using bupivacaine alone or in combination with fentanylor pethidine in paediatric cleft lip repair.
45 children between the age group 5 - 60 months undergoing cleft lip surgery randomly allocated into 3 groups of 15 each received bilateral intraoral infraorbital nerve block with 0.75ml of solution. Group B received 0.25% bupivacaine; group P received 0.25% bupivacaine with 0.25mg kg -1 pethidine, group F received 0.25% bupivacaine with 0.25microgm kg -1 fentanyl. Sedation after recovery, post operative pain intensity and duration of post operative analgesia were assessed using Modified Hannallah Pain Score.
Results : The mean duration of analgesia was 17.8 hrs in Group B, 23.53 hrs in Group F and 35.13 hrs in Group P. There was statistically significant difference between the means of the three groups- ANOVA (p < 0.05).
Conclusion: Thus we conclude that addition of fentanyl or pethidine to bupivacaine for Bilateral Intraoral Infraorbital Nerve Block prolong the duration of analgesia with no complications and can be used safely in paediatric patients.

Evaluation of intubating conditions with varying doses of propofol without muscle relaxants
p. 27
Mangesh S Gore, Kalpana D HarnagalePMID :21804701Background: Since 1988 anaesthesiologist have proved that induction dose of propofol is sufficient to intubate patient without muscle relaxants. Propofol is unique in having property to suppress airway reflexes better than any other agent. Therefore study was undertaken to evaluate clinically acceptable intubating conditions with different doses of propofol without muscle relaxants.
Patients and Methods: 90 ASA grade I and II patients posted for elective surgery requiring general anesthesia divided randomly into group I (propofol 2 mg kg -1 ); group II (2.5 mg kg -1 ); groupIII (3mg kg -1 ). Premedication with inj.Glycopyrollate, inj.Ranitidine, Inj.Ondensetron; inj.Midazolam and inj.fentanyl was done. After waiting for 5 minutes, induction dose of propofol was given followed by inj.lignocaine 90 seconds prior to intubation. Intubating conditions were assessed and hemodynamic changes were recorded at various levels.
Results: Ideal intubating conditions were obtained in 96.7%of patients in group II (2.5 mg kg -1 propofol) and 100% in group III (3 mg kg -1 propofol). We found that clinically acceptable intubating conditions can be achieved with 2.5 mg kg -1 and 3 mg kg -1 propofol without significant hemodynamic changes and 100% success can be obtained with 3 mg kg -1 of propofol
Conclusion: Ideal intubating conditions without muscle relaxants can be achieved with propofol 3 mg kg -1 with fentanyl 2 ΅g kg -1 and lignocaine 1.5 mg kg -1 without significant hemodynamic changes.

p. 31
Shahla Haleem, Neeraj K Singh, Shyam Bhandari, Dheeraj Sharma, S Hussain AmirPMID :21804702Background: This study was undertaken to compare the effects on intrauterine resuscitation by table tilt versus pelvic tilt position after spinal anaesthesia for Caesarian Section.
Patients & Methods: Fifty ASA I and II patients who fulfilled the eligibility criteria were enrolled in the study and were divided into two groups: group W (Pelvic tilt with wedge under right hip and group L- (15 0 left lateral table tilt) and received spinal anaesthesia. The following parameters were recorded. Heart rate (HR), mean arterial pressure (MAP) at baseline, 2mins, 5 min and then 5 min thereafter. Mean height of block, Total no. of segments blocked, Onset Time of sensory block (in Minutes), ephedrine doses, incidence of hypotension & bradycardia, APGAR score at 1& 5 Minutes.
Results : The decrease in MAP was much more in wedged position as compared to table tilt position also the incidence of hypotension was 40% in wedged position as compared to 12% in table tilt position. Mean height of block, Total no. of segments blocked, and boluses of inj. ephedrine used were more in the wedged position than in table tilt position.
Conclusion: Wedge placement caused increased incidence of hypotension and higher blockade after spinal anaesthesia as compared to left lateral table tilt position, there was no adverse effects on foetus and patients tolerated wedge better than left lateral table tilt position. Also surgery was easier to perform after wedge placement.

p. 35
Ruchi Gupta, Simmerpreet Kaur, Saru Singh, KS AujlaPMID :21804703Background: Post operative analgesia in patients undergoing lower limb surgery is very essential for immediate postoperative pain relief which can be provided by oral or parentral medication, epidural analgesia, local blocks etc.The study was designed to evaluate the efficacy of epidural butorphanol and tramadol for postoperative pain relief.
Patients & Methods: This was randomized, prospective, double blind study was conducted on 60 patients, ASA grade I&II, age 18-60 undergoing lower limb surgeries after approval from hospital ethics committee. Group allocation - Group I I (n=30) received 2 mg butorphanol as bolus epidurally, 1 mg for top up dose. Group II (n=30) received 100mg tramadol as bolus, 50 mg for top up. All the drugs were diluted to 10 ml normal saline & the observer was blinded to the drugs given. Postoperatively VAS, sedation score, vitals & side effects were observed. Top ups were given on achieving VAS>4. Diclofenac 75mg was given as rescue analgesia.
Results : Duration of analgesia was 5.35±0.29 hr and 6.25±1.58 hrs in Butorphanol and Tramadol groups respectively and the difference was found to be statistically significant. Pain scores were also significantly lower statistically in Group I as compared to Group II. Sedation scores were significantly higher in butorphanol group, whereas nausea vomiting was seen in tramadol group only (4 patients).No other side effects were observed.
Conclusions: Both butorphanol and tramadol were effective for relieving postoperative pain, however quality of analgesia & patient satisfaction was more with butorphanol.

p. 39
Komaljit Kaur Ravi, Tej K Kaul, Suneet Kathuria, Shikha Gupta, Sandeep KhuranaPMID :21804704Background: Epidural anaesthesia is being increasingly used to provide anaesthesia for surgery on the lower abdomen, perineum and lower extremities. However success of the epidural technique depends upon the correct identification of epidural space. [2] We conducted a study to find the distance from skin to the epidural space and its correlation with body mass index, to improve the success rate.
Patient and Methods: 120 adults patients belonging to ASA physical status I and II in the age group of 18-70 years, scheduled for surgery and or pain relief under epidural block, were taken up for the study. 60 patients of either sex were further subdivided into 2 subgroups of 30 patients each having BMI less than 30 or more than 30. The distance from skin to epidural space was measured as the distance between rubber marker and tip of Tuohy's needle.
Results: It was found that with increase in Body mass Index, the distance from skin to the epidural space also increases. The distance from the skin to the epidural space does not depend on the age or the sex of the patients.
Conclusions: We formulated predictive equation of depth of epidural space from skin in relation to BMI based on linear regression analysis as: Depth (mm) = a + b (BMI). Where a = 17.7966 and b = 0.9777.

A comparison of different doses of gabapentin to attenuate the haemodynamic response to laryngoscopy and tracheal intubation in normotensive patients
p. 43
Usha Bafna, Vipin K Goyal, Ashish GargPMID :21804705Background: Laryngoscopy and intubation evokes a transient but marked sympathetic response manifesting as increase in heart rate, blood pressure & arrhythmias. We conducted a study to compare the effect of different doses of gabapentin on hemodynamics associated with laryngoscopy and intubation.
Patients & Methods: Ninety normotensive patients (ASA I and II) between 20-60 years undergoing elective surgery requiring intubation were randomly allocated into three groups of 30 patients each. Group I received oral placebo, Group II received 600 mg of gabapentin and Group III received1000 mg of gabapentin, with sip of water 1 h prior to surgery in the operation theatre. Patients were premedicated with Glycopyrrolate, midazolam and fentanyl and induction was done with thiopentone sodium and succinylcholine. Heart rate, systolic, diastolic and mean arterial pressure were recorded at baseline, 0, 1, 3, 5 and 10 min after intubation.
Results: MAP and HR were significantly increased in patients receiving placebo and 600 mg gabapentin after laryngoscopy and intubation compared to baseline value and Group III. Significant decrease in MAP was seen just after intubation, 1, 3, 5 and 10 min after (P < 0.001, P < 0.001, P < 0.05, P < 0.05 and P < 0.05 respectively) in Group III compared to Groups I and II. HR was significantly decreased within 10 min of intubation (P<0.001)) in Group III compared to Groups I and II.
Conclusion: Gabapentin1000 mg given 1 h before operation significantly attenuated the haemodynamic response to laryngoscopy and intubation in normotensive patients.

A comparison of equisedative infusions of propofol and midazolam for conscious sedation during spinal anesthesia - A prospective randomized study
p. 47
Abhiruchi Patki, VC ShelgaonkarPMID :21804706Background : Supplemental sedation with an intravenous agent is often required to allay fear and anxiety in patients subjected to spinal anesthesia .We studied and compared the properties of propofol and midazolam as equisedative continuous infusions.
Patients & Methods: 100, ASA grade 1 and 2 patients, 18 to 60 years of age, undergoing spinal anesthesia, were randomly allocated to receive either propofol 1mg/ml or midazolam 0.1mg/ml in 50ml syringes through syringe pump. The infusion rates were titrated in order to maintain a desired sedation score of 4 on the Observer's assessment of alertness/ sedation scale. Anxiety score was assessed at regular intervals by a single observer in all cases, using a 100mm visual analog scale.Intraoperative and postoperative amnesia was assessed using visual task of recall of pictures and verbal task of recall of words.
Results: Propofol infusion was found to be superior to that of midazolam as it showed a statistically significant faster onset in achieving the desired sedation score, significantly lower mean anxiety scores, a clear headed, rapid recovery and significantly lesser postoperative impairment of recall, but midazolam infusion was seen to be associated with deeper intraoperative amnesia over the former which was beneficial.
Conclusion: Equisedatine infusion of propofol & midazolam as an adjunct & spinal anesthesia offer good anxiolysis and cardio respiratory stability. Propofol her faster onset & recovery while midazolam provides better intraoperative annesia.

Evaluation of acute normovolemic hemodilution and autotransfusion in neurosurgical patients undergoing excision of intracranial meningioma
p. 54
Imtiaz A Naqash, MA Draboo, Abdul Qayoom Lone, Showkat H Nengroo, Altaf Kirmani, Abdul Rashid BhatPMID :21804707Background : Several blood conservation strategies have been tried with the purpose of reducing homologons blood transfusion.
Patients & Methods : In a prospective randomized study, the potential benefits of acute normovolemic hemodilution (ANH) with autologous transfusion were investigated as a blood conservation technique in surgical excision of intracranial meningioma. Over a period of 2 years, 40 patients undergoing excision of intracranial meningioma were randomly assigned to two groups of 20 patients each. Group I (Control Group) received conventional homologous blood intraoperatively and were not subjected to ANH. In Group II (ANH Group), Acute Normovolemic Hemodilution was initiated to a target hematocrit of 30% after induction of anesthesia. Parameters studied included changes in hemoglobin, hematocrit and hemodynamic parameters.
Results : The mean value of blood withdrawn in ANH group was 802.5 ± 208 ml. This was replaced simultaneously with an equal volume of 6% Hydroxyethyl starch to maintain normovolemia. There was no statistically significant variation in mean hemoglobin levels between the two groups at various stages of study. Hematocrit decreased significantly in both the groups at various stages as compared to preoperative values , the decrease being more but insignificant in group II. Changes in heart rate and mean blood pressure were similar and without statistically significant differences in either group at various stages of study. The amount of surgical blood loss in group I was 835.29 ± 684.37 ml, as compared to 865 + 409.78 ml in group II. The difference was statistically insignificant (p>0.05). The mean volume of homologous blood transfused in group I was 864.71 ± 349.89 ml, as compared to 165 ± 299.6 ml in group II which was statistically significant (p<0.05). In group II (ANH Group) only 5 patients (25%) required homologous blood whereas in group I I all patients (100%) needed homologous blood.
Conclusion : We conclude that acute normovolemic hemodilution up to a target hematocrit of 30% is safe and effective in reducing the need for homologous blood in neurosurgical patients undergoing excision of intracranial meningioma.

Comparison of propofol based anaesthesia to conventional inhalational general anaesthesia for spine surgery
p. 59
LD Mishra, SK Pradhan, CS PradhanPMID :21804708Background : Often conventional Inhalational agents are used for maintenance of anaesthesia in spine surgery. This study was undertaken to compare propofol with isoflurane anaesthesia with regard to haemodynamic stability, early emergence, postoperative nausea and vomiting (PONV) and early assessment of neurological functions.
Patients & Methods: Eighty ASA grade I &II adult patients were randomly allocated into two groups. Patients in study group received inj propofol for induction as well as for maintenance along with N 2 O+O 2 and the control group patients received inj thiopentone for induction and N 2 O+O 2 +isoflurane for maintenance. BIS monitoring was used for titrating the anaesthetic dose adjustments in all patients. All patients received fentanyl boluses for intraoperative analgesia and atracurium as muscle relaxant. Statistical data containing haemodynamic parameters, PONV, emergence time, dose of drug consumed & quality of surgical field were recorded and compared using student t' test and Chi square test.
Results: The haemodynamic stability was coparable in both the groups. The quality of surgical field were better in study group. Though there was no significant difference in the recovery profile (8.3% Vs 9.02%) between both the groups, the postoperative nausea and vomiting was less in propofol group than isoflurane group (25%Vs60%). The anaesthesia cost was nearly double for propofol than isoflurane anaesthesia.
Conclusion: Haemodynamic stability was comparable in both the groups. There was no significant difference in the recovery time between intravenous and inhalational group. Patients in propofol group were clear headed at awakening and were better oriented to place than inhalational group.

Evaluation of spinal and epidural anaesthesia for day care surgery in lower limb and inguinoscrotal region
p. 62
Asha Gupta, Sarabjit Kaur, Ranjana Khetarpal, Haramritpal KaurPMID :21804709Background: Day care surgery is still in its infancy in India. Both regional and general anaesthesia can be used for this. Central neuraxial blocks are simple cheap and easy to perform. This study was done to evaluate usefulness of spinal and epidural anaesthesia for day care surgery.
Patients & Method: 100 patients were randomized to either spinal (n=50) or epidural (n=50) group anaesthetized with either 0.5% hyperbaric 2ml bupivacaine or 0.5% 20ml bupivacaine respectively. In spinal group 27 gauze quincke needle and in epidural group 18 gazue tuohy needle was used. Both the groups were compared for haemodynamic stability, side effects, complications, postanaesthesia discharge score (PADS), time taken to micturate, total duration of stay in hospital and patient satisfaction score for technique.
Results: We observed that spinal anaesthesia had significantly early onset of anaesthesia and better muscle relaxation (p<0.05) as compared to epidural block otherwise both groups were comparable for haemodynamic stability, side effects or complications. Although more patients in spinal group (64% vs 48%) achieved PADS earlier (in 4-8 hours) but statistically it was insignificant. Time to micturition (6.02 0.55 v/s 6.03 0.47 hours) and total duration of stay (7.49 1.36 v/s 8.03 1.33 hours) were comparable in both the groups.
Conclusion: Both spinal and epidural anaesthesia can be used for day care surgery. Spinal anaesthesia with 27 gauze quincke needle and 2ml 0.5% hyperbaric bupivacaine provides added advantage of early onset and complete relaxation.

Intrathecal sufentanil versus fentanyl for lower limb surgeries - A randomized controlled trial
p. 67
Poonam Motiani, Sujata Chaudhary, Nitin Bahl, AK SethiPMID :21804710Background: To compare the efficacy and safety of intrathecal sufentanil or fentanyl as adjuvants to hyperbaric bupivacaine in patients undergoing major orthopaedic lower limb surgeries in terms of onset and duration of sensory block, motor block and post-operative pain relief.
Patients & Methods: Ninety patients were recruited in this Prospective, randomized double blind study to receive either intrathecal sufentanil 5 μg (Group S), fentanyl 25 μg (Group F) or normal saline 0.5 ml (Group C) as adjuvants to 15 mg of 0.5% hyperbaric bupivacaine. The onset and duration of sensory and motor block were assessed intraoperatively. The pain scores were assessed postoperatively. Duration of complete and effective analgesia was recorded. The incidence of side effects such as nausea, vomiting, pruritus, shivering and PDPH was recorded.
Results: The Demographic data, hemodynamic and respiratory parameters were comparable in the three groups. There was a significantly earlier onset and prolonged duration of sensory block in the sufentanil and fentanyl groups. The duration of complete and effective analgesia were also significantly prolonged in the fentanyl and sufentanil groups. Pruritus was noticed in the study groups (Groups S&F).
Conclusions: Intrathecal sufentanil (5 μg) and fentanyl (25 μg), as adjuvants lead to an earlier onset and prolonged duration of sensory block. The duration of effective analgesia with intrathecal sufentanil and fentanyl as adjuvants to hyperbaric bupivacaine is longer than that of bupivacaine alone.

Comparative evaluation of ketamine - propofol, fentanyl - propofol and butorphanolpropofol on haemodynamics and laryngeal mask airway insertion conditions
p. 74
Asha Gupta, Sarabjit Kaur, Joginder Pal Attri, Nisha SainiPMID :21804711Background: Laryngeal mask airway is a non invasive supraglottic device which has led to a radical change in the management of modern general anaesthesia. Propofol as a single agent is unsatisfactory and to overcome problems associated with LMA insertions. In the present study, we evaluated the haemodynamic changes and laryngeal mask airway insertion conditions comparing ketamine and opioids as adjuncts to propofol.
Patients and Methods: 90 patients were randomly divided into 3 groups of 30 each. In Group PK-ketamine 0.5mg kg -1 , in Group PF-fentanyl 1ug kg -1 and in Group PB - butorphanol 20ug kg -1 was given intravenously immediately before induction with propofol 2.5 mg kg -1 . Jaw relaxation was assessed according to Young's criteria and the overall conditions according to modified Scheme of Lund and Stovener.
Results: The mean total dose of propofol required in Group PK was 160.37 ± 15.75mg, in Group PF 156.22 ± 17.18 mg and in Group PB 140.08 ± 18.97 mg. The incidence of absolute jaw relaxation was highest in Group PB (93.33%) patients, intermediate in Group PF (53.33%) patients and lowest in Group PK i.e. 36.66% patients. Excellent insertion conditions were observed in 12 (40%) patients in Group PK and 13 (43.33%) patients in Group PF and in 26 (86.67%) patients in Group PB. Group PK showed more rise in systolic and diastolic blood pressure and heart rate post LMA insertion as compared to Group PF and Group PB.
Conclusion: It is concluded that addition of butorphanol to propofol for LMA insertion provided absolute jaw relaxation and excellent insertion conditions with stable haemodynamics Side effects like coughing, gagging, lacrimation and laryngospasm were lower as compared to the other two groups.

Epidural labour analgesia using bupivacaine and clonidine
p. 87
K Syal, RK Dogra, A Ohri, G Chauhan, A GoelPMID :21804714Background: To compare the effects of addition of Clonidine (60 μg) to Epidural Bupivacaine (0.125%) for labour analgesia, with regard to duration of analgesia, duration of labour, ambulation, incidence of instrumentation and caesarean section, foetal outcome, patient satisfaction and side effects.
Patients & Methods: On demand, epidural labour analgesia was given to 50 nulliparous healthy term parturients (cephalic presentation), divided in two groups randomly. Group I received bupivacaine (0.125%) alone, whereas Group II received bupivacaine (0.125%) along with Clonidine (60 μg). 10 ml of 0.125% bupivacaine was injected as first dose and further doses titrated with patient relief (Numerical Rating Scale <3). Top ups were given whenever Numerical Rating Scale went above 5.
Results: There was statistically significant prolongation of duration of analgesia in Group II, with no difference in duration of labour, ambulation, incidence of instrumentation and caesarean section or foetal outcome. Also clonidine gave dose sparing effect to bupivacaine and there was better patient satisfaction without any significant side effects in Group II.
Conclusion: Clonidine is a useful adjunct to bupivacaine for epidural labour analgesia and can be considered as alternative to opioids.

Randomized double-blind comparison of ketamine-propofol and fentanyl-propofol for the insertion of laryngeal mask airway in children
p. 91
Ranju Singh, Madhur Arora, Homay VajifdarPMID :21804715Background: Till date, different combinations of adjuncts with induction agents have been tried for Laryngeal Mask Airway (LMA) insertion; yet, the ideal combination that provides the best insertion conditions with minimal side effects has not been identified, particularly in children.
Patients & Methods: Hundred paediatric ASA grade I and II patients, aged 3-12 years, were randomly allocated to receive intravenously either fentanyl 2μg kg -1 (Group F, n=50) or ketamine 0.5 mg kg -1 (Group K, n=50), before induction of anaesthesia with propofol 3.5 mg kg -1 . Arterial blood pressure and heart rate were measured before induction (baseline), immediately before induction, immediately before LMA insertion, and at 1, 3 and 5 minutes after LMA insertion. Following LMA insertion, the following six subjective endpoints were graded by a blinded anaesthetist using ordinal scales graded 1 to 3: mouth opening, gagging, swallowing, head and limb movements, laryngospasm and resistance to insertion. Duration and incidence of apnoea was also recorded.
Results: The incidence of resistance to mouth opening, resistance to LMA insertion and incidence of swallowing was not statistically significant between the two groups. Coughing/ gagging was seen in 8% patients in group K as compared to 28% patients in group K. Limb/ head movements were observed in 64% patients in the fentanyl group and in 76% patients in the ketamine group. Laryngospasm was not seen in any patient in either group. Incidence of apnoea was 80% in the fentanyl group and 50% in the ketamine group. The heart rate, systolic blood pressure, diastolic blood pressure and mean arterial pressure were consistently higher in the ketamine group as compared to the fentanyl group.
Conclusion: The combination of fentanyl (2μg kg-1) and propofol (3.5mg kg-1) provides better conditions for LMA insertion in children than a combination of ketamine (0.5 mg kg-1) and propofol (3.5mg kg-1).

Ambulatory laparoscopic tubal ligation: A comparison of general anaesthesia with local anaesthesia and sedation
p. 97
Lokesh Gupta, SK Sinha, Maitree Pande, Homay VajifdarPMID :21804716Background: To compare the anaesthetic techniques for laparoscopic tubal ligation using either general anaesthesia with LMA or a combination of local anaesthetic and intravenous sedation, this study was conducted on 60 ASA-1/2 patients in the age group of 20-40 years.
Patients & Methods: 60 ASA grade I & II female patients undergoing laparoscopic tubal ligation on a day care basis were randomly divided in two groups- group I (GA using LMA, n=30), group II (Local anaesthesia, n=30). Both groups received similar premedication. General anaesthesia in group I was induced with propofol 2-3 mg kg -1 and following LMA insertion, the anaesthesia was maintained with 0.5-1.5% halothane. In group II the incision site was infiltrated with 10 ml of 1.5% lidocaine with adrenaline and patients were sedated with intravenous midazolam 0.07mg kg -1 and ketamine 0.5 mg kg -1 . A rescue dose of 0.15 mg kg -1 of ketamine was given in group II if the patient complained of pain or discomfort during the procedure. Diclofenac sodium 1 mg kg -1 was used for postoperative analgesia in both the groups. All patients were observed in the PACU until they met the discharge criteria.
Results: The demographic profile was similar in both the groups. The induction to skin incision time was significantly more in group I (5.13 ±0.93 min vs 3.01 ±1.86 min in group II). The decrease in pulse rate and blood pressure (systolic and diastolic) was also significant in group I. The incidence of intraoperative bradycardia was 16.7% and 10% in group I & group II respectively. The changes in SpO 2 during the procedure, recovery time and time to meet discharge criteria were comparable in both the groups. The incidence of PONV was 20% & 3.3% in group I and 10% & 6.6% in group II respectively. All patients in both the groups required postoperative analgesics.
Conclusions: Both the techniques were found to be comparable for laparoscopic sterilization, however a longer induction to skin incision time and higher incidence of PONV and shivering in GA group makes LA with sedation a better choice.

Optimization of subarachanoid block by oral pregabalin for hysterectomy
p. 101
Monica Kohli, T Murali, Rajni Gupta, Parveez Khan, Jaishri BograPMID :21804717Background: 80% of patients undergoing surgical procedures experience postoperative pain 1 and requires adequate pain relief. Nowadays drugs like COX2 inhibitors and calcium channel modulators (Pregabalin and Gabapentin) are been increasingly used for postoperative pain management effectively. We conducted this study to find whether preoperative pregabalin has any effect in postoperative analgesic requirement in patients undergoing hysterectomy under spinal anaesthesia.
Patients & Methods: This randomized, double-blind, placebo-controlled trial was conducted in 150 patients undergoing hysterectomy under spinal anaesthesia, divided in three groups - Group I (PO) - Control group, Group II (P150) received 150 mg pregabalin and Group III (P300) received 300 mg pregabalin. We used VAS for anxiety, Ramsay sedation scale and VAS for patient satisfaction regarding pain relief.
Results: There was significant reduction in anxiety in groups P (150) and P (300) than placebo group P (0) during intraoperative and postoperative period than preoperative period. There was significant sedation seen in groups P (150) and P (300) than placebo group P (0). First rescue analgesia in group P (300) was202.42±6.77 and in group P (150) was176.38±4.80on average, group P (0) was131.38±5.15. Dizziness was 44.44% in group P (300), 36.11% in group P (150), and 19.44% in group P (0). Patient satisfaction was better in P (300) group than other two groups.
Conclusions: Pregabalin being an oral drug which would be easy for the patients to take and also its prolongation of the neuraxial block helps in immediate postoperative analgesia and further reduction of other parentral analgesics. Pregabalin 150mg would be the optimal preemptive dose for hysterectomy under spinal anaesthesia.
