Filter by:Theoretical framework: Hypotension during surgery directly impacts patients' postoperative outcomes and complications. Decrease in blood pressure measurements secondary to anesthetic drugs is an expected scenario in most surgical cases. Moreover, hypovolemia secondary to fast pre-operative period may facilitate post-induction hypotension which can be compensated by fluid bolus pre-operatively.
Attending physicians often supervise novice junior residents in a direct one-to-one format. Alternatively, a senior resident can be paired with a new trainee under the non-direct (but immediately available) supervision of an attending physician. Resident supervision has been considered an important step towards independent practice. Both models are ubiquitous in the United States, but no study to date has been performed if one model is better than the other with respect to supervision scores.
the purpose of this study is to evaluate the effectiveness of administration of pregabalin 2 hours preoperatively on the onset and the duration of the spinal anesthesia in total knee arthroplasty and the role of pregabalin in postoperative analgesia.
This study adopts the null hypothesis (There is no difference in pain perception during local anesthesia injection with the buzzy device in comparison to the conventional technique).
Aim of this study is to characterize the pharmacokinetics of dexmedetomidine in supine, anesthetized adult patients after intranasal dosing.
This is a single centre, prospective feasibility study and pilot randomised controlled trial of patients scheduled for elective intermediate or major non-cardiac surgery. The investigators plan to randomise up to 200 patients who meet the inclusion criteria to standard care or to personalised perioperative care based on pharmacogenomic testing for drugs commonly used in anaesthesia and postoperative pain management e.g., opioids - morphine, oxycodone and tramadol; anti-emetics - metoclopramide and ondansetron; and non-steroidal drugs - celecoxib and ibuprofen. The investigators hypothesise that pharmacogenomic testing is feasible prior to elective surgery and through 'personalised prescribing' for precision tailored perioperative care the investigators will improve patient's postoperative quality of recovery, including pain management.
The arteriovenous fistula creation (AVF creation) surgery is essential among patients with end stage renal disease who require hemodialysis. The fistula usually locates at forearm, and is created by connecting artery and vein through surgery. Patients undergone hemodialysis through the fistula six weeks later if fistula becoming mature, which means patent vessel diameter and enough flow for hemodialysis. The primary failure rate of arteriovenous fistula creation is about 20% to 40% according to previous research data. Thrombosis is the most common cause of fistula failure, which require surgical intervention after arteriovenous fistula surgery. Anesthetic technique influences surgical outcome of arteriovenous fistula. General anesthesia, regional anesthesia, and local anesthesia are both wide-used methods. Regional anesthesia with nerve block remains the most popular method for arteriovenous fistula creation. The vessel dilation effect of regional anesthesia helps not only dilatation of artery and vein, but also the fistula itself, and promotes the successful functional dialysis. Various type of nerve block are used as anesthetic method for AVF creation surgery. People requiring hemodialysis usually have multiple underlying disease involving other major organ such as heart, lung, liver, and the endocrine system. They are more vulnerable to systemic intravenous anesthetic medication. The metabolic rate and pharmacodynamics of local anesthetic may also alter due to multiple systemic disease when compared with healthy adults. The optimal concentration of lidocaine for AVF creation when using axillary block has not yet been studied. This research is conducted for dosing response of different concentration of lidocaine when using axillary block for AVF creation surgery. We aim to investigate the optimal low effective concentration, the MEC90, which defined as 90% of patients can tolerate the operation at this concentration.
Remimazolam has shown promising results for sedation in colonoscopy . Alfentanil is widely used in the analgesia of ERCP . The purpose of the study was to determine the 90% Effective Dose of Remimazolam for Duodenoscopy Insertion During ERCP With Alfentanil 10µg/kg
The study is conducted to evaluate the effect of Ibuprofen sustained release premedication on the success of buccal infiltration anaesthesia, intaroperative pain and post operative pain in mandibular molars with symptomatic irreversible pulpitis and apical periodontitis
The purpose of our study is to determine if monitoring sedation (how asleep patients are under general anesthesia) using a device called a Sedline Monitor affects the amount of anesthesia patients receive.
