Background: Spinal anesthesia is the preferred anesthetic technique for cesarean deliveries. But there is a dosage dilemma regarding block to the desired level and preventing hypotension. We aim to study effects of fixed dose with height and weight-adjusted dose of intrathecal 0.5% hyperbaric bupivacaine during elective cesarean section. Methods: Eighty-eight singleton term parturients were enrolled and divided into two groups, Group FD (Fixed Dose) and CD (Calculated Dose) in this prospective, double-blind, randomized controlled trial. Group FD received 2.2 ml and CD received a height and weight adjusted calculated dose based on Harten's chart. Hemodynamic changes, onset time to sensory block to T6, maximum block in 20 minutes, and adverse effects were compared. Results: There was a significant reduction in median drug dosage of 11mg in FD versus 9 mg in CD group. The decrease in the MAP was less in group CD (14.5±2.98) mmHg compared to (17.6±4.66) mmHg in group FD (P= 0.03). The median onset time of spinal block to T6 in group FD of 2 minutes with IQR (2-3) was faster than Group CD 4 minutes with IQR (3-5). The spinal block extended above T4 in the larger number of parturients 23 (52 %) in Group FD than in three (6.8%) in group CD (p<0.05). Significantly larger number 20 (45.45 %) in group FD developed hypotension than seven (15.9 %) in Group CD. Bradycardia and vomiting were also found in group FD. Conclusions: This calculated dose provided the desired level of the spinal block and also restricted spinal block level with a distinct advantage of less hypotension.

Introduction: The study compared spinal anesthesia using intrathecal hyperbaric bupivacaine between height and weight adjusted dose and fi xed dose during caesarean section. Methods: A hundred parturients, who had given their consent and were scheduled for elective caesarean section under spinal anesthesia, were randomly assigned into two groups. We adjusted the intrathecal dose of heavy bupivacaine (0.5 %) according to the height and weight of patients (Group AD) from Harten’s dose chart developed from the Caucasian parturients and the fi xed dose (2.2 ml) was used in Group FD patients. Keeping the observer blinded to the study groups, the onset time to sensory block up to T5, haemodynamic changes, side effects, and fetal outcome were observed. Results: The median onset time of spinal block in Group FD was faster than in Group AD (6 min vs. 4 min; p = 0.01). The spinal block level extended above T3 level in a signifi cantly (p < 0.05) larger number of patients 12 (24 %) in Group FD than in one (2 %) patient in Group AD. A signifi cantly (p < 0.05) larger number of patients, 32, (64 %) in Group FD had hypotension than in 15 (30 %) patients in Group AD. The lowest recorded SAP (101 ± 6 mm Hg) in Group AD was higher than in Group FD (96 ± 6.7 mm Hg). Nausea and vomiting were more pronounced in Group FD patients. Conclusions: The bupivacaine dose was signifi cantly reduced on its dose adjustment for the body weight and height of patients for cesearean section. This adjusted-dose use suitably restricted spinal block level for cesarean section with a distinct advantage of less hypotension and with a similar neonatal outcome as fi xed compared with the dose use. keywords: caesarean section; low-dose hyperbaric bupivacaine; spinal anesthesia.

Abstract Background Spinal anesthesia is the most popular procedure in the field of anesthesiology. Subarachnoid block is the preferred anesthetic technique for cesarean section, being simple to perform and economical with rapid onset. Lower incidence of failed block, less drug doses, minimal neonatal depression and decreased incidence of aspiration pneumonitis are added advantages of spinal anesthesia. Objectives The study aims to compare the postoperative analgesic efficacy of Fentanyl versus Nalbuphine when used with intrathecal injection of 0.5% hyperbaric bupivacaine in spinal anesthesia in patients undergoing cesarean section as the primary objective and compare intraoperative hemodynamic changes and postoperative pruritus and shivering as the secondary objectives. Methods and material After Approval was obtained from the research ethics committee of faculty of medicine, Ain Shams University and after obtaining a written informed consent. Fifty adult females underwent elective cesarean section with spinal anesthesia, their ages ranged between 18-45 years old and classified as ASA I and II were enrolled in the study at obstetrics and gynecology Ain Shams university hospital over 4 months. The patients were randomly divided using computer generated randomization into two groups 25patients in each (n = 25), Group A received intrathecal injection of 2 ml of 0.5% hyperbaric bupivacaine plus 0.5 ml fentanyl (25 μg); Group B received intrathecal injection of 2 ml of 0.5% hyperbaric bupivacaine plus 0.5 ml nalbuphine (0.8 mg) Results The main significant findings in this study was that fentanyl has a more rapid onset of motor block (5.63±0.25 minute in fentanyl group versus 5.88±0.19 minute in nalbuphine group), while nalbuphine produces less perioperative side effects as: shivering (7 patients in fentanyl group versus 1 patient in nalbuphine group), pruritis (6 patients in fentanyl group versus 1 patient in nalbuphine group), nausea and vomiting (5 patients in fentanyl group versus 1 patient in nalbuphine group). Regarding perioperative hemodynamic parameters and postoperative analgesia, they were comparable between the 2 groups. Conclusions We concluded that either intrathecal nalbuphine (0.8 mg) combined with (10 mg) Bupivacaine or intrathecal fentanyl (25 µg) combined with (10 mg) Bupivacaine improves intraoperative analgesia and prolongs early postoperative analgesia in cesarean section with significantly lower incidence of side effects as shivering, pruritis, nausea and vomiting in Nalbuphine.

Background: Spinal anesthesia with hyperbaric bupivacaine provides a dense neural block in cesarean delivery but associated with side effects like hypotension, bradycardia nausea and vomiting. Addition of low dose fentanyl with low dose of hyperbaric bupivacaine may decrease the in­cidence of these complications. The aims of study was to compare the hemodynamic parameters (blood pressure and heart rate), nausea and vomiting with low dose intrathecal hyperbaric bupivacaine with fentanyl vs a conventional dose of intrathecal hyperbaric bupivacaine in patient undergoing elective cesarean section. Methods: Seventy-four pregnant women aged 20-35 years old which un­derwent elective cesarean section at Chitwan Medical College were ran­domized into two groups. One group received spinal anesthesia with 8mg of0.5% hyperbaric bupivacaine and 25μg fentanyl and another group re­ceived 12mg 0.5% bupivacaine. Results: The mean age, baseline heart rate, systolic and diastolic blood pressure were comparable in both groups. Significant difference in hypo­tension (24.31% vs. 62.16%, p<0.05) and Nausea and vomiting (16.20% vs. 27%, p<0.05) were found in bupivacaine-fentanyl group versus a conven­tional dose of spinal bupivacaine group. Conclusions: Low dose of bupivacaine with Fentanyl provides good spinal anesthesia for cesarean section with less hypotension, nausea and vomit­ing in comparison to bupivacaine alone.

Introduction: Spinal anesthesia is considered a reasonable choice for cesarean section. Bupivacaine and ropivacaine have been used as intrathecal drugs alone or in combination with various opioids. Ropivacaine is considered a valid and safe alternative to bupivacaine for spinal anesthesia. Objectives: To compare the efficacy and safety of hyperbaric ropivacaine with hyperbaric bupivacaine in spinal anesthesia for elective cesarean section. Methodology: Sixty pregnant women undergoing elective cesarean section were allocated into two groups. Group R received 3 ml of 0.5% hyperbaric ropivacaine (2 ml 0.75% plain ropivacaine mixed with 1 ml of 25 %dextrose) and Group B received 2.5 ml of 0.5% hyperbaric bupivacaine. Both the groups were compared in terms of onset of sensory and motor block, regression of sensory and motor block, duration of analgesia and side effects. Results: The onset of sensory block was comparable in both groups but was statistically insignificant. The onset of motor block in Bupivacaine(7.53 ± 1.72) min was faster when compared to Ropivacaine group(14.33 ± 6.19) min. Regression of sensory and motor block both were faster in Ropivacaine group. Duration of analgesia was longer in Bupivacaine group(131.17 ± 32.95)min than Ropivacaine group(125.33 ± 30.54)min. Conclusion: Ropivacaine can be used as an alternative to Bupivacaine for spinal anesthesia in cesarean section but has a shorter duration of sensory and motor block.
