Filter by:The goal of this observational study is to evaluate preoperative measures of abdominal circumference in patients admitted for a cesarean section. The main questions it aims to answer are: - Can preoperative abdominal circumference predict patients with difficult spinal anesthesia - Can preoperative abdominal circumference predict the occurrence of maternal hypotension during cesarean section Participants will be examined preoperatively in terms of visibility and palpation of spinous processes, abdominal circumference will be measured in the supine and sitting positions with other clinical parameters. Spinal anesthesia will be performed by the same experienced anesthesiologist with a standardized procedure. The number of skin punctures, needle reorientations, traumatic Cerebrospinal fluid, need for a paramedian approach or failure will be recorded. Maternal blood pressure and vasopressor requirements will also be monitored.
This study is a prospective, double-blind prospective randomized controlled trial comparing mepivacaine and bupivacaine spinal anesthesia for same-day discharge readiness following a unilateral primary elective TKA procedure. Study data will be collected during the patient's hospital stay for their TKA procedure, and the primary outcome of same-day discharge readiness will be assessed the day of surgery. Patients will also be contacted at Day 3 post-op to assess for any complications, current level of pain, and pain medication utilization.
The aim of the study was to evaluate the efficacy of lavender aromatherapy in reducing pre-operative anxiety in patients undergoing surgical procedures under spinal anesthesia. This was a prospective double blinded randomized controlled trial. After patient's approval, the anxiety level was assessed preoperativetively with Visual Analogue scale-anxiety and APAIS scale. To rule out any lavender sensitivity, all subjects were given a skin patch test. This was accomplished by applying a drop of lavender oil to the back of the hand and covering it with a Tegaderm dressing to prevent inhalation and spread of the oil. After randomisation and allocation, the investigators prooceeded with the intervention preoperatively. In the operating room, the acte under spinal anethesia was performed. Then we collect data postoperatively.
The purpose of this study is to compare the incidence of hypotension between remimazolam and propofol for intraoperative sedation in patients undergoing hip surgery with spinal anesthesia.
Study of the impact of preoperative oral rehydration on the incidence of spinal anesthesia-induced hypotension for scheduled cesarean section.
The project will apply the methods of clinical observation experiment to study the central transport characteristics of flurbiprofen axetil by detecting S-flurbiprofen and R-flurbiprofen concentrations in cerebral-spinal fluid(CSF) after intravenous injection of flurbiprofen axetil in elderly patients.
Hypotension is a common complication in pregnant women after spinal anesthesia and related with the dose of local anesthetic. Injecting small dose local anesthetic into subarachnoid space can decrease the incidence of hypotension, but increase the risk of incomplete analgesia and muscle relaxation. The investigators hypothesize there is an optimal dose of bupivacaine and ropivacaine for subarachnoid injection in pregnant women, which can cause enough anesthesia and obviously decrease the incidence of hypotension without prophylactical prehydration and vasopressors. To verify this hypothesis, full-term pregnant women who were scheduled for elective cesarean section were recruited.Combined spinal-epidural anesthesia was performed for pregnant women after written informed consents. The dose of bupivacaine or ropivacaine is small and depends on height of pregnant women. The blood pressure, heart rate, respiratory rate, SpO2 and fetal heart rate were recorded and the blood flow volume of uterine artery was monitored The sensory and motor block were evaluated. After delivery, umbilical blood samples were taken for blood gas analysis. APGAR scores and neurological behavior of infant were evaluated and recorded. In the intraoperative period, side-effects and requirement for sedation, epidural injection or general anesthesia were noted. The quality of anaesthesia (judged by the anaesthetist), the quality of muscle relaxation (judged by the surgeon) and the degree of intraoperative comfort (judged by the patient) were recorded as excellent, good, fair or poor.
This study is to investigate on the objective relevance between bispectral index (BIS) and Observer's assessment of alertness/sedation (OAA/S) scale in patients sedated with Midazolam, propofol and dexmedetomidine during spinal anesthesia. Also, we will evaluate the reflection of actual sedation levels on BIS monitoring.
1. Adequate sedation with classical sedative agents, propofol 2. Sedation with propofol may induce paradoxical excitement response in heavy alcohol drinkers 3. Dexmedetomidine, α2 receptor agonist, may provide adequate sedation in heavy alcohol drinkers
