Filter by:The aim of this research project is to evaluate whether olfactory identification impairment is a reliable predictor of preoperative frailty and of postoperative complications and mortality in a population of older patients scheduled for elective surgery. 1. The investigators will measure preoperative olfactory identification function and evaluate whether olfactory impairment predicts frailty, using the Edmonton Frail Scale and handgrip strength. 2. The investigators will analyze whether preoperative olfactory impairment predicts postoperative complications and mortality.
Previously published studies show that adding intrathecal morphine to general anesthesia can reduce the postoperative pain and length of stay (LOS) in varies types of surgery. A recent meta-analysis showed that the addition of intrathecal morphine at doses below 500µg did not increase the risk of respiratory depression compared with a control group receiving intravenous opioids. Epidural analgesia is uncommonly used for robot-assisted laparoscopic procedures due to the limited surgical trauma. In addition, the risks associated with the epidural itself such as infection and spinal hematoma are thought to outweigh its possible benefits for these procedures. At Linkoping University Hospital a combination of general anesthesia and intrathecal morphine in robot-assisted laparoscopic radical prostatectomy and in robotic-assisted laparoscopic cystectomy is now routinely used in order to improve postoperative recovery. However whether this approach is beneficial in other types of robotic-assisted urological procedures is unknown. Therefore the investigators aim to conduct a feasibility study for the use of intrathecal morphine combined with general anaesthesia in adult patients undergoing elective urologic laparoscopic robot-assisted surgery at Linkoping University Hospital. The investigators will include 30 patients in the study. The specific aims are to investigate the feasibility and sensitivity of Quality of Recovery 15 (QoR15), as an outcome tool measuring postoperative well-being in this patient cohort. The investigators will also investigate the feasibility of other outcome measures such as postoperative pain, post-anesthesia care unit LOS, occurrence of pruritus and hospital LOS. For planning of the timeframe of the future interventional study the investigators will use this feasibility study to examine the inclusion rate of study patients.
Rationale There is ongoing controversy over the optimal treatment and rehabilitation strategy of an acute Achilles tendon rupture (ATR). The highest general complication rate is reported in patients treated with percutaneous repair and early mobilization. Objectives The purpose of the study is to compare the results of two ways of postoperative regimen after treatment with the modified and biomechanically significantly stronger percutaneous repair under local anesthesia. Methods & Population All the consecutive patients with an acute complete Achilles tendon rupture who will agree to take part in a study will be randomized after a modified percutaneous repair under local anesthesia into functional group (FG), using a modified brace and immobilization group (IG), wearing a rigid plaster, in both groups for the period of 6 weeks. After that they will follow the same (standardized) rehabilitation protocol. Major and minor complication rate, diameter of the healed tendon, active and passive ankle range of motion (using neutral zero method), standing heel-rise test (with 25 repetition within a minute for a grade of normal) and clinical outcome using American Foot and Ankle Society (AOFAS) hindfoot-ankle score, return to the previous activity level, presence of associated complaints and subjective assessment (scored as good, fair or poor) will be assessed. Time frame This will be a 4-year study with a 3-year follow-up. Expected outcomes: There will be no differences in demographic parameters (age, gender, side and mechanism of the injury) between groups. Patients in the FG will reach sooner final range of motion (ROM) and muscular strength without limping and will be (subjectively) more satisfied with the treatment. There will be no statistically significant differences observed between groups according to the number of complications and in the end functional results with return to pre-injury activities.
Postoperative complication rates in patients undergoing pancreaticoduodenectomy remain high although the operation techniques have developed a lot in recent years. There is evidence that restrictive intraoperative fluid therapy could decrease postoperative complication rates but the results of the former studies have been somewhat controversial. The aim of this study is to examine whether the intraoperative and postoperative fluid therapy affect to the postoperative complication rates in patients undergoing pancreaticoduodenectomy.
Variety of physical therapy treatments have been used after open abdominal surgery to improve cardiopulmonary and physical function as well as to reduce the incidence of postoperative pulmonary complications. This study intends to determine the effect of early physical therapy interventions on post-operative recovery profile, post-operative ileus and incisional pain following abdominal hysterectomy.
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 term postoperative pulmonary complication is the development of any complications affecting the respiratory system after anesthetic and surgery procedures. The ARISCAT risk assessment score is a seven-variable regression model that divides patients into low, moderate, and high-risk groups. In this study, the investigators aimed to investigate the effectiveness of the ARISCAT risk scoring index in predicting postoperative pulmonary complication development in patients scheduled for major abdominal cancer surgery.
Aims: To investigate the incidence of bleeding complications during oral surgical procedures in patients medicated with DOACs. To investigate the perioperative and postoperative bleeding volume during oral surgical procedures in patients medicated with DOACs. To examine whether increased perioperative bleeding volume complicates the planned intervention, thereby prolonging the operation time. Previous studies have shown that the incidence of healthcare-consuming bleeding complications following oral surgical procedures in patients who are prescribed warfarin is approximately 4% (9). To investigate whether the incidence is higher or lower by the intake of DOAC it is considered to be sufficient with 100 patients in each group. The groups consist of patients who are prescribed warfarin, DOACs, as well as a control group. Hypothetical outcomes: The incidence of bleeding complications and the perioperative and postoperative bleeding volume during oral surgical procedures in patients medicated with DOACs are higher compared to patients medicated with warfarin and patients taking no anticoagulants. Increased perioperative bleeding volume complicates the planned intervention, thereby prolonging the operation time. Clinical relevance: The study will serve as a basis for the development of treatment guidelines for patients who medicate with DOACs. If it turns out that the oral surgery procedure presents no increased risk of complications and that the bleeding volume does not complicate the surgery significantly, it may be recommended that patients who medicate with DOACs whom are in need of oral surgical procedures seek ordinary dental care.
Postoperative pancreatic fistula(POPF) is the most common complication of pancreaticoduodenectomy (PD). Sometimes POPF is associated with biliary fistula(BF), or "mixed" fistula. The purpose of this study is to assess whether the severity of the fistulae, when present, is decreased with an external biliary stent in place.
The primary aim of the current study is to assess the effect of continuous wireless vital sign monitoring with generation of real-time alerts, compared to blinded monitoring without alerts on the cumulative duration of any severely deviating vital signs in patients admitted to general hospital wards after major surgery. We hypothesize that continuous vital signs monitoring, and real-time alerts will reduce the cumulative duration of severely deviating vital signs.
