Background: When performing spinal anesthesia for cesarean section, it is important to determine the appropriate anesthetic dose as well as to predict the level of spinal anesthesia. In this study, it was hypothesized that some anthropometric measurements may be related to maximum sensory block and hemodynamic changes. Objectives: The aim of this study are to find maternal anthropometric values that are correlate with the level of spinal anesthesia. Methods: Maternal anthropometric measurements, including height, weight, supine and standing abdominal circumference (AC), and hip circumference, were recorded before spinal anesthesia for cesarean section. Spinal anesthesia was induced by administering 8 mg of 0.5% hyperbaric bupivacaine and 20 μg of fentanyl at the L3-L4 interspace. The level of sensory block was determined using pin-prick at 1, 5, 10, and 15 minutes after spinal anesthesia. The sensory block level and hemodynamic adverse events were analyzed in relationship to anthropometric measurements. Results: The supine AC/height ratios significantly correlate with the maximal sensory block level at 5, 10, and 15 minutes after the injection of spinal anesthetic (p = 0.001, p < 0.001 and p < 0.001, respectively). Further, there were significant correlations between body mass index (BMI) and sensory block level at every assessment (p = 0.041, p = 0.002, p = 0.001 and p < 0.001, respectively). When comparing the groups with and without hypotension, BMI, weight, and supine AC/height ratio were found to be significantly higher in the group with hypotension (p = 0.002, p = 0.004 and p = 0.006, respectively). Conclusions: We conclude that BMI and AC/height ratio correlate with the sensory block level of spinal anesthesia for cesarean section.

Background. The behaviour of isobaric levobupivacaine in relation to gravity when used in obstetric spinal anesthesia is unclear.Methods. 46 women with ASA physical status 1 undergoing cesarean section were randomly allocated to 2 groups. Spinal anesthesia with 12.5 mg levobupivacaine was performed in the sitting position in all women. Those in the first group were placed in the supine position immediately after the injection, while those in the second group were asked to remain seated for 2 minutes before assuming the supine position. The sensory block level, the onset of sensory and motor blocks, the regression of the sensory block for 2 dermatomes of the sensory block, the first request for analgesics, and the regression of motor block were recorded.Results. No differences in onset times, sensory level, or Bromage score were observed between the two groups. The time of first analgesic request was earlier in the seated group (supine131±42 min, seated106±29 min,P=.02).Conclusion. Isobaric levobupivacaine in women at term produces a subarachnoid block the dermatomal level of which does not depend on gravitational forces.

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.

Objective This meta-analysis was performed to evaluate the effect of spinal anesthesia (SA) using bupivacaine combined with dexmedetomidine (DEX) in cesarean section, analyze the adverse drug reactions induced by this mixture, and provide a reference for rational drug use. Methods Randomized controlled trials were obtained from the PubMed, Cochrane Library, and Embase databases. The primary outcome measure was the time to the highest sensory block level (min), and the secondary outcome measure was adverse effects. Results The time to the highest sensory block level was significantly shorter in the bupivacaine-DEX group than in the control group (standardized mean difference, −0.23; 95% confidence interval, −0.43 to −0.03). The incidence of shivering during the process of anesthesia, especially at a dose of 5 µg DEX, was significantly lower in the bupivacaine-DEX group than in the control group (odds ratio, 0.26; 95% confidence interval, 0.14–0.49). No significant differences were observed in the symptoms of hypotension, bradycardia, nausea/vomiting, or pruritus. Conclusion Compared with the use of bupivacaine alone for SA in cesarean section, adding dexmedetomidine during SA can significantly shorten the onset time and decrease the rate of shivering during anesthesia.

Background: Cesarean section (CS) is one of the most common surgical procedures in female patients. Authors aimed to evaluate the postoperative analgesic efficacy of adding intrathecal fentanyl to bupivacaine, and its effect on the onset and duration of spinal anesthesia along with its effect on mother and neonate.Methods: Study was performed on 60 cesarean section parturients divided into two groups. Group F received 2 ml of 0.5% hyperbaric bupivacaine (10 mg) plus 0.4 ml fentanyl (20 µg), and Group B received 2 ml of 0.5% hyperbaric bupivacaine (10 mg) plus 0.4 ml of normal saline. The parameters taken into consideration were pain scores, analgesic requirement, hemodynamic stability and side effects.Results: It was found that duration of sensory block was prolonged in fentanyl group (111 minutes vs 86 minutes, p<0.001). Duration of effective analgesia (174.36 minutes vs 127.81; p value <0.001) were also found to be prolonged in Group F with requirement of fewer postoperative analgesics (1.02 vs 2.76, p=0.03). There was not much difference in the occurrence of side effects in both the groups.Conclusions: Addition of fentanyl to intrathecal bupivacaine for cesarean section increases the duration of postoperative analgesia without increasing maternal or neonatal side effects.

Background: Spinal anesthesia is the most common method of the regional block in cesarean section, because it is easy to perform, economical produces rapid onset of anesthesia, and good muscle relaxation, and most importantly, it gives immense pleasure to the conscious mother. To improve the quality of subarachnoid block, intrathecal opioids are used as adjuvants to Bupivacaine. Fentanyl has a rapid onset of action as a lipophilic opioid following intrathecal administration. Because of high lipid solubility, it undergoes rapid uptake by the spinal cord, and hence the chances of delayed respiratory depression are less. Methods: We randomly selected 60 patients belonging to the American Society of Anesthesiologists (ASA) class I and II, who are scheduled for elective LSCS. These patients were divided randomly into two groups of 30 each. Group B received 10mg of 0.5% hyperbaric bupivacaine (2ml). Group BF received 7.5mg of 0.5% hyperbaric bupivacaine (1.5ml) with 25mcg of Fentanyl (0.5ml). Lumbar puncture was performed at the level of L3-L4 with 23 Guage Quincke Babcock's needle with the patient in the right lateral position. The sensory block was assessed with the loss of pin prick sensation, and the motor block was set using the Bromage scale technique. We also recorded the hemodynamic parameters like pulse rate, blood pressure, oxygen saturation. Results: No significant statistical difference was found in demographic data between the two groups. Group BF showed early onset of the sensory block with a P value of 0.001. Time taken to attain peak sensory level was early in the BF group with a P value of 0.001. The total duration of sensory block and duration of effective analgesia was longer in the BF group with a P value of 0.001. The onset of motor blockade was early in the bupivacaine only group with a P value of 0.02. Conclusion: The intrathecal fentanyl 25mcg reduces the dose of 7.5 mg of 0.5% hyperbaric Bupivacaine for spinal anesthesia in cesarean section, thus reducing the incidence of side effects associated with it. By its synergistic effect with 0.5% hyperbaric bupivacaine, it provides better excellent sensory blockade and postoperative analgesia, good hemodynamic stability, less incidence of complications like Nausea, vomiting, and shivering without compromising the safety of mother and fetus in comparison to intrathecal 10mg of 0.5% hyperbaric Bupivacaine alone.

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.
