Filter by:Obesity is a chronic disease that affects quality and duration of life negatively. It's not clearly known the effects of low flow anesthesia on cerebral oxygenation with high-risk morbidly obese patients. In this study, it was aimed to compare the effects of general anesthesia with low flow (0,75 L/min) and normal flow (1,5 L/min) on cerebral oxygenation and depth of anesthesia in morbidly obese patients in bariatric surgery.
Conventionally General anaesthesia remains the choice for the majority of open abdominal surgical procedures, and regional anaesthesia is preferred only for patients who are at high risk under general anaesthesia . The main reason for selecting spinal anaesthesia as the first choice for laparoscopic cases was its advantages over general anaesthesia which include uniform total muscle relaxation, a conscious patient, economical, relatively uneventful recovery, pain free early postoperative period and the protection from potential complications of general anaesthesia. The main debatable point, however, seems to be the status of respiratory parameters among the two modes of anaesthesia during laparoscopic surgery. In this context it can be stated that spontaneous physiological respiration during spinal anaesthesia would always be better than an assisted respiration as in general anaesthesia. The pneumo-peritoneum induced rise in intra-abdominal pressure including pressure on the diaphragm and carbon dioxide induced peritoneal irritation are the factors to be considered
Prospective, randomized study, including full term parturients scheduled for caesarean section under spinal anesthesia. Spinal anesthesia was performed in sitting position with a 25 G spinal needle and all patients received 15 ml/kg of crystalloid intravenously during the spinal block. Baseline hemodynamics: heart rate, systolic and diastolic blood pressure were recorded before spinal anesthesia and intraoperatively. Postspinal hypotension, defined as decrease of Systolic blood pressure>20% from the baseline value, was managed using Ephedrine increments 6 mg/3min in patients of GE group or by 5 mcg Norepinephrine/3min for the patients of GN group. Intraoperative hemodynamic data of the 2 groups were compared.
Children who undergo surgery routinely for surgery that risk high levels of circulatory changes (eg heart surgery) is currently used routinely monitoring as regional oxygenation technology of the brain (NIRS). Near infrared spectroscopy (NIRS) is a technique for measuring regional oxygen saturation, indirect autoregulation of brain. We know that reduced oxygenation of the brain can occur with severe immediate blood loss. We in the research group has been able to note that in children who undergo surgery for cranioplasty interventions <1 year old, when they have ongoing excessive bleeding, decreases oxygenation in the brain and sometimes sharply before we can replace the loss of blood, even the blood pressure can be adequately maintained. Perioperative hypovolemia is a risk factor upset autoregulation of brain. Respect of which the mean arterial pressure (MAP) required to maintain intact autoregulation during general anesthesia still lacks a scientific consensus. By illuminating the skin and underlying tissue with infrared light in the spectra of 700 to 1100nm, it is possible to measure regional oxygen saturation in various tissues. At cerebral measuring sensor is placed frontally, just below the hairline. INVOS then returns the absolute values of cerebral oxygen saturation frontally in the area where the sensor is placed. A frontal placement may in some cases be impractical / impossible and thus limits the ability to monitor the brains of children with different types of surgery or body positions. At certain cranioplastic intervention surgery a frontal placement is not always possible, partly because of surgical technic reasons, but also that the child may have to lie prone during surgery. An alternative placement of INVOS sensor could mean greater opportunities to monitor cerebral oxygen saturation and thus increase patient safety within the mentioned categories of patients. An occipital location is practically possible in many cases. The purpose of this study is to investigate whether a occipital located sensor can measure cerebral oxygen saturation in a reliable manner.
