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.

Background: Several methods are used for the prevention or decreasing the incidence of spinal anesthesia hemodynamic complications. Ondansetron is a 5HT3 receptor antagonist with known efficacy on preventing nausea and vomiting and probably on intrathecal opioid-induced pruritus. The present study aims to evaluate the effects of intravenous Ondansetron on the attenuation of blood pressure and heart rate, by 5HT3 blocking in vagal nerve endings and effect on Bezold Jarish reflex. Material and Methods: One hundred and two candidates for elective cesarean section were randomized into 2 groups of 51 cases, the Ondansetron group received 4mg Ondansetron intravenously before performing spinal anesthesia, and placebo group received 2cc sterile water. Hypotension was defined: Systolic blood pressure less than 100 MmHg or fall more than 20% from primary BP which was treated by administration of Ephedrine in case of any. In both groups, Ondansetron effect was studied on hypotension occurrence, bradycardia, consumed Ephedrine amount, pruritus, nausea and vomiting. Results: There were no statistically significant differences in systolic/diastolic blood pressure, Mean Arterial Pressure, heart rate and pruritus in both groups (P=0.081).Nausea and vomiting in the first 10 minutes after spinal anesthesia were lesser in Ondansetron group (P= 0.001). Mean consumed Ephedrine was significantly lesser in Ondansetron group (5.8 mg in Ondansetron and 10.7 mg in placebo group, P=0.009). Conclusion: Ondansetron  given  intravenously  with  antiemetic  dose  (4  mg)  decreases  mean consumed Ephedrine and nausea and vomiting after spinal anesthesia, but does not have an influence on blood pressure, heart rate and pruritus.[GMJ. 2016;5(1):13-18]

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.

The severity of postoperative pain and hemodynamic changes during and post-cesarean section have a direct effect on the neonatal and maternal condition. This study aimed to compare pain severity, hemodynamic changes, and patient satisfaction following two anesthesia techniques in elective cesarean section. In this blinded study, 60 women who were candidate for cesarean section were allocated into two equal groups of general anesthesia (GA) and spinal anesthesia (SA). Systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), and O2 Saturation at pre cesarean (T0), the uterine incision time (T1), end of surgery (T2), 6h (T3), 12h (T4), and 24 hours post-cesarean (T5) were measured. A Visual Analog Scale assessed post-cesarean pain, 6, 12, and 24 hours post-cesarean. Gender, birth weight, first- and fifth- minutes’ apgar score was recorded in the checklists. The VAS score was significantly higher in the GA group at 6h, 12h, and 24 hours post-cesarean (P=0.014, P=0.002, P=0.017, respectively). SBP and DBP at T1 in the GA group were significantly higher than in the S.A group (P<0.001). The heart rate at T0 and T1 in the GA group was lower than the SA group (P=0.001, P=0.045 respectively). The difference between the apgar scores of the two groups was not significant. SA for cesarean section was associated with lower postoperative pain, systolic and diastolic blood pressure. However, the two groups had no significant difference in terms of patients’ satisfaction and apgar scores. © 2019 Tehran University of Medical Sciences. All rights reserved.

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.

Spinal Hypotension

Background Because ephedrine infusion (2 mg/min) does not adequately prevent spinal hypotension during cesarean delivery, the authors investigated whether adding phenylephrine would improve its efficacy. Methods Thirty-nine parturients with American Society of Anesthesiologists physical status I-II who were scheduled for cesarean delivery received a crystalloid preload of 15 ml/kg. Spinal anesthesia was performed using 11 mg hyperbaric bupivacaine, 2.5 microg sufentanil, and 0.1 mg morphine. Maternal heart rate and systolic blood pressure were measured at frequent intervals. A vasopressor infusion was started immediately after spinal injection of either 2 mg/min ephedrine plus 10 microg/min phenylephrine or 2 mg/min ephedrine alone. Treatments were assigned randomly in a double-blind fashion. The infusion rate was adjusted according to systolic blood pressure using a predefined algorithm. Hypotension, defined as systolic blood pressure less than 100 mmHg and less than 80% of baseline, was treated with 6 mg ephedrine bolus doses. Results Hypotension occurred less frequently in the ephedrine-phenylephrine group than in the ephedrine-alone group: 37% versus 75% (P = 0.02). Ephedrine (36+/-16 mg, mean +/- SD) plus 178+/-81 microg phenylephrine was infused in former group, whereas 54+/-18 mg ephedrine was infused in the latter. Median supplemental ephedrine requirements and nausea scores (0-3) were less in the ephedrine-phenylephrine group (0 vs. 12 mg, P = 0.02; and 0 vs. 1.5, P = 0.01, respectively). Umbilical artery pH values were significantly higher in the ephedrine-phenylephrine group than in the group that received ephedrine alone (7.24 vs. 7.19). Apgar scores were similarly good in both groups. Conclusion Phenylephrine added to an infusion of ephedrine halved the incidence of hypotension and increased umbilical cord pH.

Background Angiotensin II may prove useful in treating regional anesthesia-induced hypotension in obstetric patients, because it causes less uterine vasoconstriction than do other vasoconstrictor drugs (such as phenylephrine). This study compared (1) maternal blood pressure and heart rate and (2) fetal status at delivery in parturients given either prophylactic angiotensin II or ephedrine infusion during spinal anesthesia for elective cesarean delivery. Methods Fifty-four women were randomized to receive either angiotensin II or ephedrine infusion intravenously during spinal anesthesia for elective cesarean section delivery. Simultaneous with subarachnoid injection, infusion of angiotensin II (2.5 microg/ml) or ephedrine (5 mg/ml) was initiated at 10 ng x kg(-1) x min(-1) and 50 microg x kg(-1) x min(-1), respectively. The rate of each infusion was adjusted to maintain maternal systolic blood pressure at 90-100% of baseline. Results Cumulative vasopressor doses (mean+/-SD) through 10, 20, and 30 min were 150+/-100, 310+/-180, and 500+/-320 ng/kg in the angiotensin group and 480+/-210, 660+/-390, and 790+/-640 microg/kg in the ephedrine group. Maternal heart rate was significantly higher (P &lt; 0.001) during vasopressor infusion in the ephedrine group than in the angiotensin group. Umbilical arterial and venous blood pH and base excess were all significantly higher (P &lt; 0.05) in the angiotensin group than in the ephedrine group. Conclusions Angiotensin II infusion maintained maternal systolic blood pressure during spinal anesthesia without increasing maternal heart rate or causing fetal acidosis.

the aim of current study: was Comparison of 1-and 2- minute sitting position versus immediately lying down on hemodynamic variables after spinal anesthesia with hyperbaric bupivacaine in elective cesarean section. Patients and methods: This study was performed after the approval of the Iraqi Council for Medical Specialization in anesthesia and intensive care, and after obtaining the consents from 90 pregnant women (at term) who were candidate for cesarean section with spinal anesthesia were recruited in this study. They were collected from “AL-Imamain AL-Kademain Medical City Teaching Hospital” (July 2017 – January 2018) , All patients were premedicated with 10mg IV metoclopramide and 50mg IV ranitidine , Base line blood pressure and the pulse rate were recorded initially before intervention , the Lumbar puncture was performed in the sitting position under full aseptic teqnique , For assessment of blood pressure and pulse rate, ten readings were taken at (3, 5, 10, 15, 20, 25, 30, 35,40and 60 min) using an automated noninvasive blood pressure. Pulse rate monitored by electrocardiogram and oximetry (SPO2). Results: Current study showed higher means of pulse rate than the other two groups especially at early times after anesthesia induction. On the other hand, both group A1 and A2 showed higher mean of systolic, diastolic and mean blood pressure than group B especially 3, 5, 10 and 15 minutes after anesthesia induction, so the variation of pulse rate over the time in the three groups. Group B had higher pulse rate Journal of University of Shanghai for Science and Technology ISSN: 1007-6735 Volume 23, Issue 9, September – 2021 Page-7882 than the other two groups at 3,5,10, 25 and 40 minutes with significant difference (P8 in all groups. Conclusions: This study revealed that the patient’s position is an important factor, which affects the frequency of Hypotension and the onset of sensory block , as well as Administration of spinal anesthesia for cesarean section. Based on the findings, keeping the parturient seated for 1 Or 2 minutes after spinal anesthesia, compared to immediately lying down, could decrease the frequency of hypotension.
