Filter by:The purpose of this study is to determine if a shorter-acting spinal anesthetic called mepivacaine has advantages over a longer-acting medication called bupivacaine.
The study will compare one technique of fluid administration (combined colloid preload and crystalloid colaod) with another one (crystalloid coload) during elective cesarean delivery performed under spinal anesthesia.
Pregnant women with a positive preoperative Supine stress test were found to be a subgroup at increased risk of symptomatic hypotension after spinal anesthesia
Context: The neuraxial blocks, spinal anesthesia and epidural anesthesia are among the most frequently performed procedures worldwide, and despite the advancements of medical equipment, remain dependent on experience and practice of the anesthesiologists. Although antisepsis takes part of the daily routine, there are still no solid scientific evidence of the most appropriate antiseptic for these procedures. Objective: To compare the 70% alcohol and 0.5% chlorhexidine alcohol solution in skin antisepsis for the neuraxial blocks. Methods: This is a clinical trial, a prospective, randomized study. There will be selected, consecutively, 70 patients candidates for neuraxial blocks. Patients will be randomly assigned to group A (n = 35), in which the antisepsis will be performed with alcohol 70%, and to group B (n = 35), in which the antiseptic will be performed with the 0.5% chlorhexidine in alcoholic solution. Samples will be collected with swabs in an area of 25 cm² for bacterial cultures three times: in pre-antisepsis moments, in the second minute after antisepsis, and immediately after the puncture. The number of colonies forming units per square centimeter (CFU / cm²) will be counted. The data will be analyzed statistically.
Considering fast-track principles, an ideal spinal anesthetic should have minimal complications and above all fast recovery so reducing in-hospital stay. Between 1/8/2015 and 1/1/2016, a total of 101 patients attending the surgeon's practice with an umbilical or unilateral inguinal hernia and no contra-indications for surgery were included in this study. Patients were given 10.5mg bupivacaine (B-group), 40mg hyperbaric 2-chloroprocaïne (C-group) or 60mg prilocaïne (P-group), each with added sufentanil (2µg). Motor block was assessed using the Bromage scale. Sensory block was measured by determining the peak level dermatome. Intraoperative hemodynamic parameters were listed. Resolution of sensory and motor block, time to void and home readiness were defined as clinical endpoints.
Spinal block leads to the reduction of systemic vascular resistance (SVR) which may effect the cardiac output. Ngan Kee et al. has showed that spina block with 0.5% hyperbaric bupivacaine for Cesarean section combined with intravenous infusion norepinephrine had higher cardiac output than those who received phenylephrine
A Randomized, Controlled, Double blind study aiming to evaluate the analgesic potentials and side effect profile of different dose levels of Dexmedetomidine added to subarachnoid bupivacaine in full-term pregnant women undergoing elective cesarean section using spinal anesthesia. The investigators ultimate goal is to find out the least effective dose which will be associated with minimal or no side effects. The primary outcome will be the time to two sensory block segment regression.
The aim of this study is to compare two different therapeutic approaches to blood pressure reduction: pharmacological vs. non-pharmacological. The setting is that of patients undergoing scheduled Cesarean section under spinal anesthesia and suffering from aorta-caval compression syndrome, which causes a sudden drop in blood pressure.
The aim of this study is to assess the efficacy of atropine in preventing nausea and vomiting after spinal anesthesia with local anesthetic and morphine for elective Caesarean section. Patients enrolling in the study will be assigned to one of three groups. One will receive a small dose of intrathecal atropine; another will receive small-dose intravenous atropine; the third group will receive placebo.
The purpose of this study is to compare the efficacy, duration of motor block until return to normal function in the non-operated leg after the start of injection, of ropivacaine 5 mg/ml and bupivacaine 5 mg/ml when used for spinal anaesthesia in patients undergoing unilateral lower limb surgery.
