Filter by:Introduction- During laparoscopic procedures surgical field exposure is one of the crucial aspects for a successful surgery. Exposure can be optimized by pneumoperitoneum, positioning of the patient and muscle relaxation. The European Association for Endoscopic Surgery has recommended using the lowest intraperitoneal pressure allowing adequate exposure of the operative field rather than using a routine pressure. A way to lower intraabdominal pressure during laparoscopic procedures is to employ a deeper level of neuromuscular blockade. Intravenous (IV) opioids such as fentanyl and remifentanil are commonly used to provide analgesia and supplement sedation during general anesthesia. In terms of analgesia, management of intraoperative stress, remifentanil exhibits similar effects to fentanyl in adult healthy volunteers and surgical patients. In clinical practice, if the surgeon asks for relaxation toward the end of the surgery, then many anesthesiologists will increase the dose of the IV opioids. In our experience the use of remifentanil achieves a better muscle relaxation and surgical space exposure with a lower intraabdominal pressure and less need for a neuromuscular blockage as compared to fentanyl. Thus, the investigators aimed to compare the use of fentanyl versus remifentanil during laparoscopic hysterectomy. Because surgical complications due to inadequate exposure are a rare event, the typical way to study this issue is to use surgeon's satisfaction score.
Spinal anesthesia is the technique of choice in transurethral prostatectomy.However,one of the common complications of spinal anesthesia is shivering which is even exaggerated in patients undergoing transurethral prostatectomy.this high incidence is most probably caused by sympathetic block and use of large amount of irrigation fluid during surgery.There are two methods to reduce shivering.Previous studies showed that intrathecal fentanyl is an appropriate method to reduce shivering.Intrathecal dexamethasone could reduce shivering by regulating immune responses.
The purpose of this study is to determine if a single dose of sublingual sufentanil is as or more efficacious than a single dose of IV fentanyl in a post anesthesia care setting.
It is used by music therapists to help the social, physical, emotional, psychological and psychological needs of patients. In a study, music has a positive effect on pain, anxiety, depression, shortness of breath, mood, facial expression and speech . The aim of this study was to investigate analgesia consumption during egg collection and postoperative period of music therapy and to compare and evaluate oxidative stress parameters in blood and follicle fluids.
The objective of the LEGO®Bricks MRI project is to study a new play-based tool for use in children preparing to undergo MRI and evaluate its ability to reduce the need for anesthesia. A randomized study design will be employed in the experimental "Child Life" (CL) group, in regard to which Child Life intervention patients will have. Age matched controls will be found retrospectively, and will be patients of the same age, undergoing their first non-contrast brain MRI with no Child Life intervention. Patients in the CL group will be prepped by a Certified Child Life Specialist with the use of one of the following 2 tools, to be randomly selected: 1. LEGO Bricks model MRI (A model of the MRI machine and adjacent control room made out of LEGO bricks) 2. Mock MRI tube (A six foot long pop-out play tunnel for children, with a diameter of around 17 inches to simulate the MRI magnet bore)
Our study is intended to compare optimal muscle tension management or conventional anesthetic management in laparoscopic cholecystectomy about surgical condition during the surgery and other conditions after surgery at POR.
Propofol is an extensively utilized intravenous sedative and general anesthetic. However, propofol has a narrow therapeutic index, and this means that there is only a small difference in the dose required to produce loss of consciousness and the dose required to produce potentially life-threatening effects such as loss of protective airway reflexes and cessation of spontaneous breathing. Moreover, there is substantial variation between individuals in the doses required to achieve these pharmacodynamic endpoints. Given the inexorable rise in demand for pediatric sedation and the increasing use of propofol in sedation protocols by non-anaesthesiologists, the purpose of this study is to refine the propofol dosing recommendations to account for pharmacogenomic variability to make procedural sedation safer for children. Experienced users already adjust for age and body weight. This study may enable further refinements according to sex and - novelly - ancestry.
Assessing the impact of anesthesia practice on global warming and carbon footprint becomes part of the standard of care and is growing concern within the anesthesia community. Global Warming Potential (GWP) is a measure of how much a given mass of greenhouse gas contributes to global warming over a specified time period. Inhaled anesthetics have various GWP20: 349 for sevoflurane and 3714 for desflurane. However, GWP20 and CDE20 alone are not sufficient to evaluate the environmental impact of anesthetic gases. Other parameters must be included in the analysis: fresh gas flow (FGF), carrier gas (air, O2, N2O) and potency of the anesthetic gas. Unfortunately, the majority of trials did not fully consider the FGF reduction and the fact that desflurane can be administered with new closed or very low-flow anesthesia circuits as opposed as the recommended 2L/min that must be used for sevoflurane according to its monography in Canada. Most of the calculations were made on a purely theoretical approach that could be different from actual measurements based on a strictly monitored anesthesia practice. When continuous and accurate gas monitoring and analysis is used as recommended nowadays, the use of closed or semi-closed-circuit anesthesia with very low FGF might allow for a reduction of more than 80% of the anesthetic gas administration and its consequent pollution. By properly monitoring the anesthesia depth and analgesia adequacy, the investigators can reduce the gas consumption. The proposed study will aim at determining whether with the help of high-quality monitoring (BIS and NOL) and high-end ventilators that allow minimal fresh gas flow, the use of desflurane remains more polluting than sevoflurane.
The aim of this study was to compare the risk of pulmonary aspiration assessed with gastric ultrasonography in elderly patients, undergoing elective surgery.
The purpose of this study is to evaluate the benefit of adding mental visualization to a training program in medical education. Undergraduate medical students will be randomized before participating in a training program on airway management during rapid sequence induction. In the control group, participants will receive traditional teaching including theoretical courses and procedural simulation. In the intervention group, in addition to traditional teaching, participants will be trained and encouraged to practice mental visualization. The main outcome will be clinical performance during a standardized high-fidelity simulation of rapid sequence induction assessed using a specific pre-established checklist.
