scholarly journals Incidence of Hypotension and Associated-risk Factors in Epidural Anesthesia With 2% Lidocaine and Epinephrine During Elective Cesarean Section, Efficacy and Safety Assessment

Author(s):  

Background: Cesarean section is a worldwide common surgery that requires anesthetic techniques. Many local anesthetics are being now used, but are associated with, dose- dependent and at different level, some side effects including toxicity. Hypotension was described as the first and threat side effect associated to neuraxial techniques. Despite many preventive strategies, it continues to challenge anesthesia providers around the world. Lidocaine was found to be less toxic compared with others commonly used and has been recommended for anesthesia procedures requiring large dose of local anesthetic including epidural anesthesia. The main purpose of this research was to determine the incidence of hypotension and identify the possible risk factors associated with it and thus, assess the efficacy and safety when lidocaine is applied together with epinephrine, in epidural anesthesia for elective cesarean delivery. Materials and methods: This retrospective observational institutional-based study, recruited 612 parturients who underwent elective cesarean section under epidural anesthesia with 2% lidocaine and 1/200000 epinephrine, at 1st affiliated hospital of Chongqing Medical University in 2019. Exclusion criteria included any contraindication to elective cesarean section delivery, general anesthesia, baseline systolic blood pressure < 100mmh and > 140 mm hg, gestational age < 37 weeks and > 42 weeks etc. SPSS 26.0 version and different appropriated tests were used for statistical analysis. P value < 0.05 was accepted as statistically significant. Results: The hypotension incidence was 13.2%, and identified factors associated with it were Baseline Systolic Blood Pressure < 120mmhg, gestational age < 40 weeks, maternal body weight ≤ 60 kg and duration of cesarean delivery (surgery) > 45 minutes. Conclusion: The variables in correlation with increased hypotension rate are baseline systolic blood pressure, gestational age, maternal weight, and surgery duration. 2%Lidocaine with epinephrine as adjuvant presented best outcomes towards both mother and neonates, was therefore efficacy and safe under the anesthetic conditions of our study.

We would like to present the first report of severe acute dystonic reaction after a single administration of metoclopramide during cesarean section under combined spinal-epidural anesthesia.  During elective cesarean section, a 30-year-old female vomited four times and was treated with 10mg intravenous metoclopramide and 8mg intravenous ondansetron.  Nausea subsided with the antiemetic treatment, but two minutes later, patient had rapid eye blinking, uncontrollable head movement, and became unresponsive.  Bolus of 50mg intravenous diphenhydramine resolved the acute dystonic symptoms within seconds.  Patient was again oriented times three, with no recollection of symptoms, and remained symptom free for the rest of admission.

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.

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]
