Active clinical trials for "Postoperative Complications"

The study consist of evaluation in cardiac surgery with cardiopulmonary bypass (CPB) setting the ability of PCO2 derived variables (ΔPCO2, ΔPCO2/C(a-v)O2 ratio), compared to lactate and ScVO2 to predict major postoperative adverse events.

This study is intended to investigate the safety and efficacy of ω-3 polyunsaturated fatty acid-based parenteral nutrition (PN) for patients with Crohn's disease.

Vascular stiffness increases as a person ages, due to the repetitive stress that is put on the vascular system which causes changes in the elasticity of the vessel walls. The increased stiffness of the arteries puts added stress on the circulatory system. This rise in stiffness has been shown to be associated with an increased risk of cardiovascular events, in both presumably healthy patients, as well as elderly patients The current method for assessing perioperative cardiac risk is the Goldman's Revised Cardiac Risk Index (RCRI). This method, however, does not include a direct measurement of arterial stiffness. Applanation tonometry is a non-invasive technique that has been shown to reliably provide indices of arterial stiffness While the use of applanation tonometry has been widely studied in general medicine, it is has not been studied for pre-operative risk assessment in surgical patients. The purpose of this investigation is to examine whether aortic stiffness is an independent risk factor for developing cardiovascular related adverse events in patients who are having major surgery under general anesthesia. Applanation tonometry will be performed on the right carotid and femoral arteries to assess carotid-femoral pulse wave velocity, a surrogate for aortic stiffness. (SphygmoCor system, AtCor Medical, Sydney, Australia). The measurement will be obtained before induction of general anesthesia in the presurgical area. Patients' medical history, intraoperative hemodynamics, and any postoperative complications will be recorded to determine significant correlations and relationships. This information will potentially help identify future patients that might be at greater risk of developing an adverse cardiovascular event following their surgical procedure.

The objective of the study is to evaluate influence of perioperative fluid therapy on Methemoglobin levels, and to changes in hemoglobin. Further, changes in Methemoglobin will be related to metabolic signs of oxidative stress (changes in blood lactate). Patients undergoing major abdominal surgery will be included into the study.

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.

The purpose of this study is to evaluate effect of high FiO2 on the development of intraoperative atelectasis in mechanically ventilated children using LUS. to investigate the correlation between lung consolidation score and patient clinical variables including pulmonary mechanics, Sao2%, ABG, and perioperative respiratory complications.

Background: This study assessed perioperative factors associated with planned and unplanned postoperative ICU admission and evaluated the outcome of the two groups. There are limited researches evaluating these factors. Hence, it is important to do an audit that assesses the perioperative factors to help creating a criteria for postoperative ICU admissions. Materials and methods: This retrospective study evaluated medical records of 68 patients above 18 years between January'2016- December'2018 that were admitted to ICU postoperatively in Sultan Qaboos University hospital in Oman. Both planned and unplanned admissions were assessed who underwent elective as well as emergency surgeries. Neurologic and cardiothoracic surgeries were excluded. Data collected included patient's demographics, social status like smoking, ASA physical status (American Society of Anesthesiologists), associated comorbidities, other perioperative factors and investigations, surgical and anesthesia details were recorded. The primary outcome studied was reasons of admission for planned versus unplanned postoperative ICU admissions. The secondary outcomes included mortality outcome and length of stay in ICU.

The aim of the trial is to study the efficacy of continuous bilateral Erector Spinae Plane Block (ESPB) in managing perioperative pain in patients who undergo elective laparoscopic colectomy.

This prospective study intends to development and validation a patient self-assessment questionnaire. The aim of the self-assessment, by questionnaire, is to estimate the risk of postoperative pulmonary complications (PPC).

In this study we aimed to define a new modified SAS is to predict the incidence of postoperative complication and mortality in major abdominal and orthopedic surgery. We also identify the effectivity of this modified scoring system composed of the duration of operation in addition to the three intraoperative parameters of SAS.
