Filter by:The Transversus Abdominal Plane (TAP) block has been used with good success to decrease postoperative pain following laparatomy. If the TAP block provides any improvement in the quality of recovery following laparoscopic hysterectomy, it could decrease the need for postoperative narcotics and allow for more outpatient hysterectomy procedures.
The current study is designed to investigate the difference of plasma orexin A levels between elderly and young patients at emergence from sevoflurane-fentanyl anesthesia who will undergo elective lumbar surgery.
Measurement of how much blood the heart pumps may be useful in guiding how much intravenous fluid to give patients during surgery. The current monitors either require special drips (arterial and/or central lines) or a probe inserted into the oesophagus (food pipe) which may limit their use. Newer monitors are available which are completely non-invasive and seem to work well in younger patients. Patients with hip fracture are elderly and frail. The investigators wish to see whether the newer non-invasive monitor works well enough compared to the current monitors in this group of patients. If it does this may allow more of these patients to be monitored in this way.
Bispectral Index Monitoring (BIS) has been proven to be effective in preventing awareness. Optimizing anesthesia level using BIS monitoring, neither to light nor to deep will probably help to shorten recovery time and reduce drug consumption. The aim of the study was to investigate the effect of BIS monitoring on extubation and recovery time, and intraoperative anesthesia consumption.
The aim of this study is to determine the minimum effective volume of local anesthetic (50:50 mixture of 0.5% levobupivacaine and 2% lidocaine) required to produce an effective US-SCB for surgical anesthesia in 50% of patients and to calculate the effective volume required to produce an effective US-SCB in 95% of the patients (MEAV95) in elderly group (>65 years) and in middle aged group (<45years) of patients.
Most researches revealed that volatile anesthetic sevoflurane has a more marked cardioprotective effect against ischemia compared with intravenous agent propofol.However, propofol has been suggested to be more benefit for attenuation of surgery-induced immunosuppression.Thus, the aim of this study was to investigate under the specific OPCAB surgical stress, the influence of 3 established anesthetic techniques: sevoflurane, propofol and combine of sevoflurane and propofol maintained anesthesia on the apoptosis of circulating lymphocytes.
This study is designed to compare the effects of alkalinized lidocaine in the endotracheal tube cuff to a bolus dose of remifentanil given prior to the emergence of anesthesia: - on the incidence of perioperative coughing - on the time needed for the emergence of a desflurane-based anesthesia - on the incidence of sore throat after extubation. The investigators hypothesis is that the use of alkalinized lidocaine in the endotracheal tube cuff will reduce the incidence of perioperative coughing after a desflurane-based anesthesia.
The Bispectral Index monitor is used in many operating rooms to provide information to the anesthesiologist about a patient's level of consciousness. The Composite Variability Index, or Composite Variability Index (CVI), is a new index that may provide the anesthesiologist with more information about the condition of the patient. The purpose of this study is to determine if a commonly used anesthetic drug (rocuronium) affects the CVI measurement differently with different doses. Rocuronium is a muscle relaxant routinely used during surgery. It is expected that the group given the highest dose of rocuronium will have diminished CVI values.
Understudied drugs will be administered to children per standard of care as prescribed by their treating caregiver and only biological sample collection during the time of drug administration will be involved. A total of approximately 7000 children aged <21 years who are receiving these drugs for standard of care will be enrolled and will be followed for up a maximum of 90 days. The goal of this study is to characterize the pharmacokinetics of understudied drugs for which specific dosing recommendations and safety data are lacking. The prescribing of drugs to children will not be part of this protocol. Taking advantage of procedures done as part of routine medical care (i.e. blood draws) this study will serve as a tool to better understand drug exposure in children receiving these drugs per standard of care. The data collected through this initiative will also provide valuable pharmacokinetic and dosing information of drugs in different pediatric age groups as well as special pediatric populations (i.e. obese).
This blinded cross-over study aimed to evaluate the efficacy of topical liposome-encapsulated lidocaine on oral mucosa.
