Filter by:Aim of the study is to compare the optimal time needed for successful tracheal intubation with immediate 8% sevoflurane and incremental sevoflurane induction in surgical pediatric patients undergoing adenotonsillectomy without using muscle relaxants or opioids
Postpartum haemorrhage (PPH) is an obstetric emergency and defined as a blood loss of ≥500ml after vaginal birth and ≥1000ml after caesarean section (CS) and/or the need for blood transfusion within 24 hours after delivery (World Health Organization, Recommendations for the Prevention of Postpartum Haemorrhage. 2007; Leduc et al., J Obstet Gynaecol Can, 2009). Since PPH is more common after caesarean deliveries than after vaginal births and the rate of CS is rising over time and will probably continue to rise, the incidence of PPH is expected to increase accordingly. A meta-analysis has shown that routine administration of an oxytocic agent after caesarean delivery leads to a reduced blood loss and decreases the risk of PPH (Cotter et al., Cochrane Database Syst Rev, 2001). The two most commonly used oxytocic drugs after operative delivery are oxytocin and carbetocin, a synthetic oxytocin-analogue. Carbetocin has the advantage over oxytocin of having a longer half-life and therefore reducing the use of additional uterotonics. Based on the findings of reduced cardiovascular side-effects with a short-infusion as compared to a bolus injection found for oxytocin (Thomas et al., Br J Anaesth, 2007), our study hypothesis is that a slower administration rate of carbetocin minimises the cardiovascular side effects without compromising the uterine tone. Therefore, we aim to investigate a short infusion of carbetocin 100 mcg applied in 100ml sodium chlorid compared to a bolus application in women undergoing primary or secondary caesarean delivery. This prospective, double-blind, randomised controlled non-inferiority trial will take place at the University Hospital Basel, Switzerland. We hypothesize uterine contraction not to be inferior (primary efficacy endpoint) and the mean arterial pressure to be higher after a short-infusion than after a bolus administration (primary safety endpoint).
Objective: To determine the efficacy of sedation schemes to sedation in patients about to undergo spinal anesthesia. Methods: Pilot study, clinical type, randomized, prospective, single-blind, in which the investigators compared three schemes for sedation in patients undergoing spinal anesthesia. Keywords: Anesthesia, Spinal Anesthesia, Conscious Sedation, Operating Rooms.
OBJECTIVE: To determine the efficacy of ketamine-propofol anesthesia in a mixture 1:2 (1 mg of ketamine per 2 mg of propofol) for short minimally invasive surgical procedures. METHODS: The investigators performed a prospective study through randomization of 77 patients undergoing short surgical procedures in two study groups: one received a mixture of ketamine-propofol in a 1:1 ratio, and the other received a 1:2 mixture. Data were stored in an Excel spreadsheet and analyzed using the statistical program Epi-Info (TM) 3.5.3. The investigators performed the comparison of qualitative and quantitative variables. KEY WORDS: ketamine, propofol, anesthesia.
