Anesthesia-handover Checklist and Perioperative Outcomes in Elderly

With the increasing number of surgical cases, intraoperative handover of anesthesia care is common and inevitable. Verbal handover from one anesthesiologist to another during surgery are being used in many hospitals. However, verbal handover is often an informal, unstructured process during which omissions and errors can occur. It is possible that an improved anesthesia handover may reduce the related adverse events. This study aims to test the hypothesis that use of a well-designed, structured handover-checklist to improve handover quality may decrease the occurrence of postoperative complications in elderly patients undergoing major noncardiac surgery.

Comparison of Karydakis and Limberg Flap Treatment of Pilonidal Sinus in Adolescent. a Prospective, Randomised Study

Pilonidal sinus disease (PSD) is a chronic inflammation and infection of the sacrococcygeal region. Produces clinic findings with abscess and discharge in the sacrococcygeal region or painful sinus tract in the natal cleft. Its incidence rate among Turkish servicemen is reported to be 8.8% in a study. Although pilonidal sinus disease is common in men, this is the opposite in adolescence. Because adolescent girls are 2 or 3 times more. Karydakis flap and Limberg flap operations widely preferred in recent years in the surgical treatment of PSD. In our study, we aim to compare these two techniques prospectively and randomly.

Extended Care in High-Risk Surgical Patient (EXCARE) Pathway in High-risk Surgical Population

High risk surgical patients are subject to complications that impact rehabilitation time, overall mortality and costs. This project proposes the creation of a post-surgery care pathway called Extended Care in High-Risk Surgical Patients (EXCARE) in the form of coordinated multiprofessional actions dedicated to high-risk non-cardiac surgical patients with the aim of improving the postoperative outcomes. The proposed pathway comprises a range of actions that include individual patient-centered risk assessment by the Anaesthesia and Perioperative Medicine Service (SAMPE) Risk Model (30-day probability of death), specialized care in Post-Anesthetic and Intensive Care Units (ICU), and also in the surgical wards performed by the nursing, anesthesia, clinic and surgery teams. This is a quasi-experiment in which the clinical effectiveness of the extended care will be analyzed using a before-and-after comparison, the primary outcome being 30-day surgical mortality and postoperative complications at day 7 defined by PostOperative Morbidity Survey (POMS), a reliable and valid survey of short-term postoperative morbidity in major elective surgery. POMS domains evaluated are: pulmonary, infectious, renal, gastrointestinal, cardiovascular, neurological, haematological and wound complications. Secondary outcomes include 30-day mortality, hospital length of stay, number of Rapid Response Team calls, unplanned postoperative ICU admission, surgical reintervention, failure to rescue and hospital readmission. High-sensitive cardiac troponin (hs-cTn) levels will be measured before surgery and daily until 48 hours postoperatively to identify patients with myocardial injury (defined as any hs-cTn concentration greater than the 99th-percentile upper reference limit).

Patient Experiences of IONM and Outcomes

Resection of brain tumours forms a large proportion of work in brain surgery. One important aspect is to minimize damage to normal brain structures during this process. This improves patient outcomes and reduces complications. To identify normal brain structures from the abnormal tumours, the brain surgeons use a 'guidance' technique called intraoperative neuro-monitoring (IONM). IONM uses various electrodes to observe spontaneous electrical activity of the brain or its reaction to a stimulus such as muscle contraction, light or sound. It is now becoming common practice for neurosurgeons to use this tool during brain and spinal surgery to provide a real-time feedback under anaesthesia to help them minimise injury to important and normal brain and spine structures. IONM interpretation needs fulfilment of multiple preconditions and major modifications to the anaesthetic to reduce its inaccuracies. This invites added risks and complications such as awareness, convulsions and heart problems under anaesthesia. A team approach between the surgeon, anaesthetist and neurophysiologist (IONM specialist) is also crucial to obtain meaningful results. Therefore, the usefulness of this technique is still not perfect. Although, benefits of IONM are obvious, information on associated complications and patient experience are not commonly found in the literature. Information on other effects such as hormonal balance and tumour recurrence are also scarce. In general, these aspects have little scientific exploration. There are anecdotal reports of recurrent seizures during IONM leading to serious heart problems, teeth and tongue damage due to grinding and postoperative calf muscle injury necessitating further surgery to save limbs. Neither of these is in the literature including unorthodox treatments such as the use of cold saline to control IONM triggered fits. This study is designed to observe complications and outcome and explore patient experiences following IONM in an observational capacity not interfering with the clinical management or treatment of these patients. The investigators intend to interview the participants after surgery, at a convenient time before leaving hospital to understand their views and experiences during and after surgery and their general progress in the following one year.

Perioperative Muscle Relaxant and Postoperative Outcomes

Muscle relaxant is usually needed for surgery. However, the optimal depth of neuro-muscular blockade is still on debate. Deep neuro-muscular blockade may benefit the patients during surgery, but may increase the risk of residual blockade after surgery. Residual blockade has been reported to increase risk of morbidity. In this study, we tend to observe the postoperative outcomes in patients undergoing abdominal surgery under general anesthesia. And to compare the outcomes in patients received different depth of neuro-muscular blockade.
