The aim of this paper is to evaluate the efficacy and safety of three different norepinephrine dosing regimens for preventing spinal hypotension in cesarean section. In this randomized double-blinded controlled study, 120 parturients scheduled for elective section delivery under spinal anesthesia were assigned to 1 of 4 groups. In the control group, patients received saline infusion. In three norepinephrine groups, the infusion dosage regimens were 5, 10, and 15 μg/kg/h, respectively. Hypotension was treated with a rescue bolus of 10 μg norepinephrine. The study protocol was continued until the end of surgery. The primary outcome was the proportion of participants that underwent hypotension. The proportion of hypotension participants was significantly reduced in the norepinephrine groups (37.9%, 20%, and 25%, respectively) compared to that in the control group (86.7%). However, the highest dose of norepinephrine (15 μg/kg/h) resulted in more hypertension episodes. In addition, blood pressure was better maintained in the norepinephrine 5 μg/kg/h and 10 μg/kg/h groups than in the control group and 15 μg/kg/h group. No significant differences in other hemodynamic variables, adverse effects, maternal and neonatal blood gases, or Apgar scores were observed among the groups. In summary, for patients who undergo cesarean delivery under spinal anesthesia, infusion of 5–10 μg/kg/h norepinephrine was effective to reduce hypotension incidence without significant adverse effects on maternal and neonatal outcomes. Clinical Trial Registration Number is ChiCTR-INR-16009452.

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: Government of Nepal has been conducting Cesarean section under “Safe Motherhood” program all over country. The purpose of this study was to evaluate the efficacy and safety of intrathecal morphine for post cesarean analgesia under spinal anesthesia.  Methods: A total of 300 parturients posted for Cesarean section under spinal anesthesia were divided into two groups of 150 each in this prospective randomized case-control study. Morphine group received 0.15 mg of intrathecal morphine mixed in 12 mg of 0.5% bupivacaine heavy while control group received 12 mg of 0.5% bupivacaine heavy alone, after proper preparation of spinal anesthesia. The parturients were assessed for first request of analgesic as per Visual Analog Scale, frequency of analgesics required within 24 hr, nausea, vomiting, pruritus, sedation and respiratory depression.Results: Postoperative analgesia was significantly greater in morphine group as compare to control group (12.1 ± 7.6 vs 3.7 ± 2.9 hr). Frequency of analgesics requirements was also significantly lower in morphine group (1.7 ± 2.0 vs 3.4 ± 8.1). Visual Analog Scale was below 4 at most of time in morphine group. The incidence of nausea, vomiting and pruritus were more in morphine group as compare to control group but without any respiratory depression. There was no significant difference in APGAR score among fetus.  Conclusion: Mixing low dose of intrathecal morphine in standard dose of spinal anesthesia effectively prolongs the duration of post cesarean analgesia and decreases the frequency of analgesics requirement without any major complication in parturients or fetus.Journal of Society of Anesthesiologists 2014 1(1): 13-17

Background Elective cesarean section decreases the likelihood of vertical human immunodeficiency virus (HIV) transmission from mother to infant. This study aimed to determine whether cesarean section done with spinal anesthesia on HIV-1-infected pregnant women taking antiretroviral therapy is associated with intraoperative hemodynamic instability, postoperative complications, or changes in immune function or HIV-1 viral load. Methods A case-controlled study was conducted over a 3-year period in a London academic hospital. Forty-four women infected with HIV-1 and a control group of 45 HIV-negative women undergoing cesarean sections were included. The main outcome measures included intraoperative blood pressure, heart rate, blood loss, and ephedrine requirements, and postoperative infective complications, blood transfusion, changes in blood HIV-1 viral load and lymphocyte subsets, and time to hospital discharge. Results There were no differences in hemodynamic stability and postoperative complications between the HIV-infected group and the controls. There was an acute postoperative increase in the CD4T lymphocyte count (P = 0.01), but the CD4T:CD8T ratio and viral load did not change. Conclusions Elective cesarean section under spinal anesthesia for women infected with HIV-1 taking antiretroviral therapy was not associated with intraoperative or postoperative complications.

Background: Spinal anesthesia is the commonest technique used in Cesarean Section (CS) and most frequently associated with maternal hypotension, for which a lot of techniques have been described to prevent but an effective method is yet to be found. Objectives; The aim was to study the effect of using a sub-anesthetic dose of ketamine to prevent post-spinal hypotension in CS delivery. Methods: This double-blinded randomized controlled study was conducted on 80 participating parturients who were ASA І, П term pregnant. All the parturients received spinal anesthesia. The parturients were then randomly divided into two equal groups (n= 40 in each); ketamine group received a sub-anesthetic dose of ketamine of 0.5 mg/kg IV bolus in 3 ml saline and control group received the same volume of normal saline IV bolus. Heart Rate (HR) and Mean Arterial blood Pressure (MAP) were recorded at baseline (5 minutes prior to the intrathecal injection), at 5, 10, 15 and 20 minutes after the injection and then every 15 minutes till the end of the operation. Incidences of hypotension and severe hypotension were recorded. The total dose of ephedrine was recorded. Ramsay sedation score was recorded at baseline then 5, 10, 15, 30, 45 minutes after injection and then at the end of the operation. Results: Compared to the control group, sedation score was significantly higher among ketamine group at 5, 10 and 15 minutes. MAP and HR were significantly higher among ketamine group at 5, 10, 15, and 20 minutes. Total ephedrine dose was significantly lower among the ketamine group. Mild hypotension and severe hypotension were significantly less frequent among the ketamine group, as all the patients in the control group had an attack of mild hypotension and 55% of this group had an attack of severe hypotension. No significant difference between both the groups regarding diplopia, nystagmus, hallucination, nausea and vomiting. Conclusion: It is concluded that ketamine in a sub-anesthetic dose is an effective agent that can be used in preventing post-spinal hypotension in parturients undergoing CS delivery.

Background: The transverses abdominis plane block (TAP block) is one of the widely used regional analgesic techniques in cesarean section. There are different variations of the procedure. The aim of the present study was to evaluate the analgesic effect of the modified surgeon assisted bilateral TAP block in patients undergoing cesarean section Patients&Methods: Sixty patients undergoing cesarean section under spinal anesthesia were randomized into two groups to receive either TAP block with 40 ml of bupivacaine 0.25%(study group) or 40 ml normal saline as placebo after obtaining informed consent. All patients will receive intravenous diclofencac75mg every 12 hrs postoperatively. Postoperatively, there was an assessment every 2hrs during the first 24hrs by the visual analogue pain scale (VAPS). Time to the first analgesic request will be measured as primary outcome and all patients will receive opioid on demand or VAPS > 4 with 25mg pethidine intramuscularly. Moreover, total opioid requirement in 24hrs will be measured as secondary outcome along with postoperative complications as nausea, vomiting and abdominal distention. Complications related to the TAP procedure will be also assessed. Results: The median (interquartile range) time to the first analgesic request in the first 24hrs postoperatively was significantly shorter in the placebo group compared to the study group; 4h (4, 6) and 24h (10, 24) with p value < 0.001. Postoperative opioid requirement was significantly higher in the control group (30/30{100%}) than the study group (13/30{43.3%}). The median (interquartile range) number of opioid doses was significantly higher in the placebo group compared with the study group; 2(2, 2) and 0(0, 1) respectively. At all points in the study, pain scores both were lower in the study group (p < 0.0001). Conclusion: The modified surgeon assisted bilateral TAP block is relatively new, safe and cost effective technique which provides adequate postoperative analgesia allowing for better maternal ambulation and better postoperative recovery.

Aims: Spinal anesthesia is the choice of anesthesia in parturient for cesarean section. This procedure is frequently associated with hypotension and the incidence varies from 70% to 80%. Maternal hypotension causes very unpleasant sign and symptoms such as nausea, vomiting, dyspnoea and sense of impending doom. Prolonged episodes of hypotension lead to organ ischemia, loss of consciousness, cardiovascular collapse and uteroplacental hypoperfusion. The aim of this study is to find out the proper data of the incidence of hypotension in parturient undergoing cesarean section in our hospital as only the estimated data is present. Methods: We retrospectively reviewed the intraoperative anesthesia record form of all the patients who underwent cesarean section under spinal anesthesia from the hospital record section from 13th April 2016 to 12th April 2017. The detailed parameters of patient’s demographic data were collected and recorded. Results: A total of 3814 parturients were included in this study. The mean age was 25.76 ± 4.74 years and mean gestational age was 39.23 ± 1.54 weeks. Post spinal hypotension was seen in 947 patients out of 3814. Thus the incidence of hypotension was 24.8%. Conclusions: The incidence of maternal hypotension is very high if prophylactic measures are not taken. The fluid preloading or coloading, left lateral uterine displacement and prophylactic vasopressors have shown to be effective in preventing postspinal hypotension.

Abstract Introduction Tobacco heating products (THPs) generate lower machine yields of toxicants compared to those found in conventional cigarette smoke. During use, these products are likely to expose users to lower levels of particulate matter and harmful and potentially harmful compounds compared with smoking cigarettes. Aims and Methods This randomized, controlled study is investigating whether biomarkers of exposure (BoE) to smoke toxicants are reduced when smokers switch from smoking cigarettes to using the glo THP in a naturalistic, ambulatory setting. Control groups include smokers who are abstaining from cigarette smoking and never-smokers. At a baseline study visit, 24-hour urine samples and spot blood samples were taken for BoE analysis, and exhaled carbon monoxide was also measured. N-(2-cyanoethyl) valine (CEVal) was used as a marker of compliance in subjects asked to refrain from combustible cigarette smoking. Subjects are being followed up at periodic intervals for 360 days; this article presents data following a planned interim analysis at day 90. Results In continuing smokers, BoE remained stable between baseline (day 1) and day 90. In both per-protocol and CEVal-compliant analysis populations, reductions in BoE were observed in subjects switching to using glo or undergoing smoking cessation. These reductions were statistically significant for a number of BoE when switching to glo was compared with continued smoking. Furthermore, in both populations, reductions observed in subjects switching to using glo were comparable to those seen with smoking cessation and were also to levels similar to those seen in never-smokers. Conclusion glo is a reduced-exposure tobacco product. Implications This clinical study builds on a previous 5-day confinement study and demonstrates that when smokers switched from smoking combustible cigarettes to using the glo THP in a naturalistic, ambulatory setting, their exposure to tobacco smoke toxicants was significantly decreased. For most BoE examined, this was to the same extent as that seen when a control group of smokers ceased cigarette smoking, or even to levels seen in never-smoker controls. This indicates that glo is a reduced-exposure product with the potential to be a reduced-risk tobacco product, when used by smokers whose cigarette consumption is displaced completely.

Background: Postpartum hemorrhage is a common and occasionally life-threatening complication of labor. Cesarean section is associated with more blood loss in compared to vaginal delivery. Despite, there is a trend for increasing cesarean section rates in both developed and developing countries thereby increasing the risk of morbidity and mortality, especially among anemic women. The objective of this study was to evaluate the effect of preoperative administration of intravenous Tranexamic acid on blood loss during and after elective cesarean section.Methods: This was a prospective, randomized controlled study with 160 eligible pregnant women of 37 or more period of gestation. They were all planned for elective cesarean section and were randomized into two groups either to receive 10ml (1gm) of Tranexamic acid intravenously or 10ml of normal saline. Blood loss was measured during and for 24 hours after operation.Results: The mean estimated blood loss was significantly lower in women treated with Tranexamic acid compared with women in the placebo group (392.13 ml±10.06 vs 498.69 ml±15.87, respectively; p<0.001). The mean difference in pre-operative and post-operative hemoglobin levels was statistically significant in the Tranexamic acid group than in the control group (0.31±0.18 vs 0.79±0.23, respectively; p<0.001).Conclusions: Pre-operative use of Tranexamic acid is associated with reduced blood loss during and after elective cesarean section. In a developing country like ours where postpartum hemorrhage is a major threat to the life of the mothers, it seems to be a promising option.
