Hemodynamic effects of carbetocin administered as an intravenous bolus or infusion during cesarean delivery

Background: Postpartum hemorrhage is the leading cause of maternal mortality. Oxytocin being the most popular uterotonic agent, has been routinely administered after both vaginal delivery and cesarean section. Carbetocin is a newer uterotonic agent and provides the benefit of a longer duration of action without additional administration post-delivery.Methods: We recruited 34 women undergoing elective cesarean section under spinal anesthesia. All patient was received spinal anesthesia using 0.5% hyperbaric Marcaine 8–10 mg in conjugation with fentanyl 20 μg in the left lateral decubitus position. Hartmann’s solution 10–15 ml/kg was administered before carbetocin. The operation started as soon as sensory block at level T4–T6 was confirmed. A non-invasive hemodynamic monitoring cuff (Finometer®) was attached to the patient’s finger soon after the induction of spinal anesthesia. Using the Finometer, we recorded the heart rate and mean arterial pressure at every 15 s, starting from 15 s before the administration of carbetocin to 5 min after. After the removal of the placenta, the bolus group was administered intravenous bolus injection of carbetocin 100 μg and the infusion group was administered carbetocin 100 μg diluted in 50 ml normal saline, over 5 min using an infusion pump.Results: The demographic data showed no significant difference between the two groups. Furthermore, there were no significant hemodynamic differences between the two groups.Conclusions: The method of administration of carbetocin does not influence its hemodynamic effects.

Background: Postoperative nausea and vomiting (PONV) is a common complication associated with the use of anesthesia. Several antiemetics are used to reduce the incidence and severity of PONV. The aim of this study is to investigate the role of dexamethasone and ondansetron to treat PONV in patients undergoing cesarean section (c-section) under spinal anesthesia. Methods: This double-blind clinical trial study was performed on patients who were referred to the operating room of Haji Karim Asali Hospital of Khorramabad for elective cesarean section in 2016-17. Upon meeting the inclusion criteria, patients were allotted into two groups (n=60). Group A received 8mg of dexamethasone and group B received 4mg of ondansetron after spinal anesthesia. The Visual Analog Scale (VAS) questionnaire and Depression-Anxiety-Stress Scale (DASS) questionnaire was used for the analysis. Patients with mild to moderate stress, anxiety, and depression were included in the study. Data were analyzed using SPSS 16 software. Results: There was no difference in the demographic data of the two groups. The mean severity of nausea in group A was significantly higher than in group B. The frequency of vomiting in group A was 20 times higher than group B, which was found to be statistically significant, p = 0.018. Concerning the type of delivery with the frequency of nausea, the results showed that the frequency of nausea in group A was 3.24 times higher than group B, however, this difference was not statistically significant, p = 0.106. Conclusion: Based on the results of this study, ondansetron had a significant effect on the alleviation of postoperative nausea and vomiting, as compared to dexamethasone in c-section surgical candidates.

Background: Several methods have been used to prevent post spinal hypotension including preloading, co-loading, use of vasopressors, placement of pelvic wedge, lumbar wedge and tilting of operating table in parturients undergoing cesarean section. We conducted a randomized controlled study to determine the hemodynamic effects of a standard pelvic wedge placed below the right hip immediately after the spinal block till the delivery of baby. Methods: One hundred consenting women undergoing elective cesarean section under spinal anesthesia were randomly allocated to wedge group (N=50) and control group (N=50). A standard wedge was placed under the right pelvis soon after spinal anesthesia till the delivery of baby in wedge group whereas the control group remained supine. Hemodynamic parameters including blood pressure, heart rate, vasopressor consumption, other side effects like nausea, vomiting and neonatal outcome were also recorded. Results: The incidence of hypotension and bradycardia was similar between groups (Wedge group 60% vs Control group 75.51%, p=0.125) before the birth of baby. The use of vasopressors (p=0.212), incidence of nausea (p=0.346) and Apgar score at 1 and 5 minutes (p=0.629, p=0.442) were also not statistically significant. None of the patients had vomiting. Conclusion: In our study, the use of right pelvic wedge immediately after spinal anesthesia was not effective in preventing post spinal hypotension in elective cesarean section.

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.

Objective: To compare patients undergoing cesarean section under spinal and general anesthesia in terms of neonatal APGAR scores and patient satisfaction. Study Design: Comparative cross-sectional study. Place and Duration of Study: Departments of Anesthesia and Gynecology and Obstetrics, Combined Military Hospital Peshawar, for six months from Mar to Aug 2019. Methodology: In this study, 120 females with a singleton pregnancy of 36-40 weeks, and requiring a non-emergency elective cesarean section were enrolled through consecutive sampling in the study. The patients were randomly allocated into two equal groups of 60 women each through random table numbers. Group A received spinal anesthesia and group B general anesthesia. APGAR score was assessed at 5 minutes after delivery, and score of ≥7 was taken as satisfactory. Patient's satisfaction level regarding anesthesia was recorded on a visual analogue scale of 0 (extremely unsatisfied) to 10 (completely satisfied), and score of ≥7 was taken as satisfactory. Results: Women receiving general anesthesia were more satisfied as compared to receiving spinal anesthesia (95% vs. 78.3%; p-value 0.007). There was no significant difference in terms of APGAR scores in general anesthesia and spinal anesthesia (83.33% versus 90%; p-value 0.283). Conclusion: After an elective caesarean section, more mothers were satisfied after receiving general anesthesia as compared to spinal anesthesia. However, both types of anaesthesia were found to be equally safe for babies born in terms of APGAR scores at 5 minutes.

Purpose: Post-anesthesia shivering is one of the most common problems after surgery and may lead to multiple complications such as hypoxemia, lactate acidosis and catecholamine release. The purpose of this study was to compare the effects of intravenous meperidine and ondansetron on postoperative shivering in patients having an elective cesarean section under spinal anesthesia. Design: Cross-sectional study Methods: In this cross-sectional study, 105 patients with the age of 18-45 years and ASA class I-II undergoing elective cesarean section were randomly assigned into three groups. Group O was administered 8mg ondansetron, group M patients were given 0.4mg/kg meperidine and group P was placebo that was administered with 2cc of saline intravenously after the delivery. The incidence and intensity of shivering and postoperative nausea was monitored and recorded by the trained nurse. The data obtained was analyzed using SPSS v18. Results: All three groups (n=35) had no significant difference in terms of age, weight and time of spinal anesthesia. Postoperative shivering was reported in 4 patients (11.4%) in group A and 3 patients (8.6%) in group B and in 14 patients (40%) in group C. The incidence of postoperative shivering was significantly less in groups A and B as compared to the placebo, p=0.03. The intensity of shivering was greater in group C as compared to groups A and B, p=0.01. The incidence and intensity of postoperative nausea was significantly less in group A, p=0.03, p<0.001, respectively, while no difference was reported in groups B and C, p<0.05. Conclusion: 8mg ondansetron and 0.4 mg/kg of meperidine are equally effective in managing postoperative shivering; however, ondansetron has an additional effect of reducing the incidence of postoperative nausea among patients undergoing caesarean section with spinal anesthesia.

Postoperative Ileus (POI) is one of the most common problems after obstetrics, gynecologic and abdominal surgeries. Sham feeding, such as gum chewing, accelerates the return of bowel function and the length of hospital stay. The present study aims to evaluate the effect of chewing gum on bowel motility in women undergoing post-operative cesarean section. Intervention study was used at the Postpartum Department of Maternity and Children Hospital, KSA. A randomized controlled clinical trial research design. Through a convenience technique, 80 post Caesarian Section (CS) women were included in the study. Data were collected through three tools: Tool (I): Socio-demographic data and reproductive history interview schedule. Tool (II): Postoperative Assessment Sheet. Tool (III): Outcomes of gum chewing and the length of hospital stay. Method: subjects were assigned randomly into two groups of (40) the experimental and (40) the control. Subjects in the study group were asked to chew two pieces of sugarless gum for 30 min/three times daily in the morning, noon, and evening immediately after recovery from anesthesia and in Postpartum Department; while subjects in the control group followed the hospital routine care. Each woman in both groups was tested abdominally using a stethoscope to auscultate the bowel sounds and asked to report immediately the time of either passing flatus or stool. Results: illustrated that a highly statistically significant difference was observed between the two groups concerning their gum chewing outcomes. Where, P = 0.000. The study concluded that gum chewing is safe, well tolerated and appears to be effective in reducing the incidence and consequences of POI following CS.
