Background: Use of adjuvant with small doses of local anesthetics is a preferred technique for spinal anesthesia for lower limb surgeries. This study tested the hypothesis that addition of small doses of clonidine augments the spinal block levels produced by hyperbaric bupivacaine in patients without affecting the side-effects. Materials and Methods: This was a prospective, randomized, double-blind study. Above 60 years patients were allocated to three equal groups. Group C received 10 mg hyperbaric bupivacaine without clonidine while Group C and Group C received 15 μg and 30 μg clonidine with 15 30 hyperbaric bupivacaine respectively for spinal anesthesia. Effect of clonidine on sensory block levels was the primary study outcome measure. Motor blockade and hemodynamic parameters were also studied. Results:Asignicantly higher median block levels were achieved in Group C (P < 0.05) and Group C (P <0.05) than Group C. Highest median 15 30 sensory block level, the mean times for sensory regression to T12 level and motor block regression were statistically signicant between Groups C15 and C and between Groups C and C. On comparison of fall in systolic blood pressure trends, there was no signicant difference in the clonidine 30 groups as compared with the control group. Conclusions: In elderly patients, clonidine when used intrathecally in doses of 15 μg or 30 μg with bupivacaine, signicantly potentiated the sensory block levels and duration of analgesia without affecting the trend of systolic blood pressure as compared to bupivacaine alone. Clonidine in doses of 30 μg however facilitated the ascent of sensory level block to unexpectedly higher dermatomes for a longer time.

Abstract Background Post-spinal anesthesia (PSA) hypotension in elderly patients is challenging. Correction of PSA hypotension by fluids either colloids or crystalloids or by vasoconstrictors pose the risk of volume overload or compromising cardiac conditions. Dexamethasone is used to treat conditions manifested by decrease of peripheral vascular resistance. The research team was the first to test the hypothesis of its role in preventing or decreasing the incidence of PSA hypotension. Methods One hundred ten patients, aged 60 years or more were recruited to receive a single preoperative dose of dexamethasone 8 mg IVI in 100 ml normal saline (D group) (55 patients) 2 h preoperatively, and 55 patients were given placebo (C group) in a randomized, double-blind trial. Variations in blood pressure and heart rate in addition to the needs of ephedrine and/or atropine following spinal anesthesia (SA) were recorded. SA was achieved using subarachnoid injection of 3 ml hyperbaric bupivacaine 0.5%. Results Demographic data and the quality of sensory and motor block were comparable between groups. At 5th, 10th minutes post SA; systolic, diastolic and mean arterial pressures were statistically significant higher in D group. At 20th minutes post SA; the obtained blood pressure readings and heart rate changes didn’t show any statistically significance between groups. The need for ephedrine and side effects were statistically significant lower in D group than C group. Conclusion Post-spinal anesthesia hypotension, nausea, vomiting and shivering in elderly patients were less common after receiving a single preoperative dose of dexamethasone 8 mg IVI than control.

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 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.

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.

Background: During caesarean section hypotension due to spinal block is secondary to the sympathetic blockade and aorto-caval compression by the uterus. It can have important consequences for the mother and may affect neonatal outcome. The present study was aimed to compare intravenous bolus doses of phenylephrine and ephedrine to treat maternal hypotension during spinal block for elective caesarean section.Methods: After fulfilling the inclusion criteria, 100 parturient were randomly allocated into two groups of fifty each. For spinal anesthesia lumber puncture was done and 12.5mg, 0.5% hyperbaric bupivacaine was given intra-thecally. In this observational study, patients who developed hypotension under spinal anesthesia were selected for the study. According to their group, patients received either ephedrine 6mg (Group E) or phenylephrine 75µg (Group P) as vasopressor. During the study, number of vasopressor boluses, hemodynamic response and time taken to recover from hypotension was noted.Results: Ephedrine and phenylephrine were used in the mean doses of 6.72±1.97mg and 91.5±31.38µg respectively. In 88% parturient single bolus dose of ephedrine was effective in treating hypotension while phenylephrine was effective in 78% parturient. There was no significant difference observed in total number of boluses used. No significant difference was seen in mean systolic blood pressure, mean diastolic blood pressure and mean arterial pressure over a given period of time in Group E and Group P. Mean systolic BP was less than 20% when compared to baseline in both the groups at different time intervals. In Group P the mean heart rate was significantly lower as compared to the Group E (p<0.05).Conclusions: Intravenous phenylephrine and ephedrine are both similar in performance in treating hypotension after spinal anesthesia for elective caesarean section and the hypotensive control offered is comparable.

Background: Pregnancy-induced hypertension constitutes a major cause of morbidity and mortality in developing nations and it complicates about 6-8% of pregnancies. Severe preeclampsia poses a dilemma for the anesthesiologist especially in emergency situations where caesarean deliveries are planned for uninvestigated or partially investigated parturients. The choice of anesthesia in preeclamptic mothers undergoing Cesarean delivery has been debated for years. General as well as regional anesthetic techniques are equally acceptable for cesarean delivery in pregnancies complicated by preeclampsia. Currently, the safety of regional anesthesia technique is well established and they can provide better obstetrical outcome. Objective: To study the outcome and elaborate the hemodynamic changes associated with spinal anesthesia in preeclampsia. Methods: The study was carried out in com ii la medical college hospital and private clinics in comilla among preeclamptic women who underwent Lower Segment Caesarean Section (LSCS) under spinal anesthesia between January 2013 and July 2017. Both emergency as well as elective cases were included in the study. Patients' records were studied and analyzed. The drug used for spinal anesthesia was hyperbaric Bupivacaine 0.5%. Subarachnoid block was performed in either L3-L4 or L2-L3 intervertebral segment with patient sitting up. Spinal needle 25G was used. The hemodynamic response (systolic blood pressure, diastolic blood pressure, heart rate) and Sp02 were observed. Results: Total of 310 cases was included in our study. Age ranged from 17 to 37 years. The duration of surgery ranged from 25mins to 100mins. According to observation, both systolic and diastolic blood pressure dropped to minimum within the initial 10 minutes of spinal anesthesia. Heart rate fluctuation was minimal with an initial small drop within 10 minutes of spinal anesthesia. Similarly, Sp02 also showed a subtle decline within 20 minutes of spinal anesthesia. Conclusion: Our study finds spinal anesthesia as a preferred method taking into account the relatively stable and better hemodynamic stability, convenience in procedure and rapid and predictable anesthesia and no risks of sudden critical hypotension.
