PURPOSE: Spinal anesthesia for caesarean delivery is often associated with hypotension. This study was conducted to evaluate the effects of rapid crystalloid (Lactated Ringer's solution; LRS) or colloid (hydroxyethyl starch; HES) cohydration with a second intravenous access line on the incidence of hypotension and ephedrine requirement during spinal anesthesia for cesarean section. METHODS: We studied 90 women with uncomplicated pregnancies undergoing elective cesarean section under spinal anesthesia...

BACKGROUND AND OBJECTIVES: Hypertrophic pyloric stenosis is a relatively common affection of gastrointestinal tract in childhood that results in symptoms, such as projectile vomiting and metabolic disorders that imply a high risk of aspiration during anesthetic induction. In this way, the carrying out of a technique with general anesthesia and intravenous rapid sequence induction, preoxygenation and cricoid pressure are recommended. After the correction of systemic metabolic alkalosis and pH normalization, cerebrospinal fluid can keep a state of metabolic alkalosis...

BACKGROUND: Although controversial, many studies have shown effectiveness of colloid loading as a substitute for crystalloids on reducing the incidence of hypotension in spinal anesthesia. This study was conducted to compare the effects of three intravenous fluid regimens on hemodynamic changes following spinal anesthesia in cesarean section. The regimens included 6% Hydroxyethylstarch 130/0.4 (HES) as a colloid and two crystalloids (lactated ringer's solution and sodium chloride 0.9%)...

BACKGROUND: Hypotension is a common problem during spinal anesthesia for cesarean delivery. Intravenous fluid loading is used to correct preoperative dehydration and reduce the incidence and severity of hypotension. Different fluid regimens have been studied but colloid preload and crystalloid co-load have not been compared. METHODS: In this randomized double-blind study, 210 patients scheduled for elective cesarean section under spinal anesthesia were randomly allocated to receive either 6% hydroxyethyl starch 130/0...

BACKGROUND: Women undergoing cesarean section are vulnerable to adverse effects associated with inadvertent perioperative hypothermia, but there has been a lack of synthesized evidence for temperature management in this population. This systematic review aimed to synthesize the best available evidence in relation to preventing hypothermia in mothers undergoing cesarean section surgery. METHODS: Randomized controlled trials meeting the inclusion criteria (adult patients of any ethnic background, with or without comorbidities, undergoing any mode of anesthesia for any type of cesarean section) were eligible for consideration...

This prospective observational study compared the effects of general and spinal anesthesia in 173 severe preeclamptic women undergoing emergency cesarean section. 146 (84.5%) patients underwent spinal anesthesia (SA) and 27 (15.5%) patients had general anesthesia (GA). Most of the patients were primigravid and nulliparous. Intraoperatively SA group required more intravenous fluid and vasopressor support, while GA group required more preoperative labetalol injection for blood pressure control. Overall 13.3% of patients required critical care, particularly GA group (44...

Isoflurane, ketamine, and propofol are common anesthetics in human and nonhuman primate medicine. However, scant normative data exist regarding the response of neonatal macaques to these anesthetics. We compared the effects of isoflurane, ketamine, and propofol anesthesia on physiologic parameters in neonatal rhesus macaques. Neonatal rhesus macaques (age, 5 to 7 d) were exposed to isoflurane (n = 5), ketamine (n = 4), propofol (n = 4) or no anesthesia (n = 5) for 5 h. The anesthetics were titrated to achieve a moderate anesthetic plane, and heart rate, blood pressure, respiratory rate, end tidal carbon dioxide, oxygen saturation, and temperature were measured every 15 min...

REVIEW
Lavenia Carpenter, Curtis L Baysinger
Anesthesia and surgery interfere with normal thermoregulation, and nearly all patients will become hypothermic unless compensatory measures are used. Preoperative patient warming and intraoperative methods using forced air and warmed intravenous fluids are important methods for maintaining patient's core temperature during the perioperative period. The benefits of maintaining normothermia include reductions in postoperative wound infection, the risk of perioperative coagulopathy, and myocardial ischemia. These advantages, demonstrated in patients undergoing general surgery, would be expected in patients undergoing gynecological surgery but have not been specifically studied in that population...

OBJECTIVE: To assess current pediatric anesthesia practice for further education from Royal College of Anesthesiologists of Thailand. MATERIAL AND METHOD: A questionnaire was sent to 500 anesthetists in public hospitals in January 2010 to investigate preoperative data, intraoperative data, postoperative pain management, ambulatory anesthesia, and pediatric anesthesia training requirement. RESULTS: Response rate was 30.6%. Preoperative fasting and infective endocarditis (IE) prophylaxis were appropriate except that half the anesthesiologists preferred giving antibiotics in non-cyanotic heart diseases and ordering complete blood count as a routine investigation in healthy patients undergoing minor surgery...

OBJECTIVE: Quantitative characterization of continuous pediatric drug infusions. BACKGROUND: The dynamics of drug delivery by continuous infusion to pediatric patients have not been systematically examined. This study extends previously described analytic models to propofol and remifentanil delivery, focusing on infants and toddlers. We postulated that infusion system dead volume, and drug and carrier flow rates, significantly influence drug delivery. METHODS: We studied effects of patient weight, infusion system dead volume, drug and carrier flow rates, along with drug stock concentration and dose, on propofol and remifentanil delivery to the circulation...

We designed a randomized, double-blinded study to determine the efficacy and safety of 0.5 mg/kg intravenous ephedrine for the prevention of hypotension during spinal anesthesia for cesarean delivery. Patients were randomly allocated into two groups: ephedrine group (n=21) and control group (n=21). Intravenous preload of 15 mL/kg lactated Ringer's solution was given. Shortly after the spinal injection, ephedrine 0.5 mg/kg or saline was injected intravenous for 60 sec. The mean of highest and lowest heart rate in the ephedrine group was higher than those of control group (P<0...

Spinal-induced hypotension remains the most common complication associated with spinal anesthesia for cesarean delivery. Recent evidence indicates that a 20-mL/kg bolus via pressurized infusion system administered at the time of subarachnoid block (SAB) (coload) may provide better prophylaxis than the traditional administration of a 20-mL/kg crystalloid infusion (preload) approximately 20 minutes before SAB; however, this method raises some concerns. We hypothesized that administering half of the fluid bolus (10 mL/kg) before and half immediately following injection of the SAB would provide benefit...

BACKGROUND: Pre-loading with hetastarch decreases the incidence and severity of hypotension after spinal anesthesia for cesarean delivery. However, pharmacokinetic studies with crystalloid predict that fluid loading should be more efficacious if rapidly administered immediately after induction of spinal anesthesia. The aim of this study was to compare pre- and co-loading of hetastarch for the prevention of hypotension following spinal anesthesia for cesarean delivery. METHODS: Forty-six healthy term parturients scheduled for cesarean delivery were randomized to receive 500 mL of 6% hetastarch intravenously, either slowly before spinal anesthesia (pre-loading) or as quickly as possible immediately after spinal anesthesia (co-loading)...

Considerable progress has been made in adapting existing and developing new technologies to enable increasingly detailed phenotypic information to be obtained in embryonic and newborn mice. Sophisticated methods for imaging mouse embryos and newborns are available and include ultrasound and magnetic resonance imaging (MRI) for in vivo imaging, and MRI, vascular corrosion casts, micro-computed tomography, and optical projection tomography (OPT) for postmortem imaging. In addition, Doppler and M-mode ultrasound are useful noninvasive tools to monitor cardiac and vascular hemodynamics in vivo in embryos and newborns...
