Filter by:The objective of this research study is to evaluate the effect of a quality improvement initiative carried out by a health system opioid stewardship task force aiming to increase clinician post-operative prescribing adherence with procedure specific guidelines that were developed using patient reported data. The feedback compares the clinician's average number of opioid pills prescribed after a given procedure to other clinicians in the health system and to the health system guideline recommended amount based on patient reported data on opioid pills taken for that procedure. The feedback also provides historical data on mean patient reported number opioid pills taken following a given procedure and on patients' ability to manage pain among those who received guideline adherent prescriptions compared with patients who received greater than the guideline recommended amount.
This study looks for a correlation between microRNAs (miRNAs) and vasoplegic syndrome after on-pump coronary artery bypass surgery.
Cardiopulmonary exercise testing (CPET) is used for preoperative risk assessment in patients with colorectal cancer who need to undergo surgery. For presentation and interpretation purposes, CPET data are averaged by using a time- or breath-based average. It is uncertain to what extent differences in data averaging methods influence the numerical value of preoperative CPET-derived variables used for risk assessment. Therefore, the primary aim of this study is to investigate the influence of different CPET data averaging intervals on the numerical values of CPET-derived variables used for preoperative risk assessment in patients scheduled for elective colorectal cancer surgery. The secondary aim is to elucidate the impact of data-averaging intervals on classification of patients into a low- or high-risk category for postoperative complications based on known risk assessment thresholds.
Cardiac surgical interventions are increasingly offered to vulnerable patients or patients living with frailty. Unfortunately, frailty has been shown to be an independent predictor of poorer outcome and increased health care resources in terms of readmission to hospital or visit to the ER after discharge. We hypothesize that the use of a comprehensive Telehealth home-monitoring program could reduce emergency room visits and re-hospitalization after heart surgery. Frailty in all patients will be determined using the Edmonton frailty scale (EFS) as is part of the current standard of care for all patients at the NBHC since 2018. We plan to implement the Telehealth intervention on all 120 consecutively enrolled patients identified as vulnerable and/or frail and discharged from hospital within 10 days of their surgery. The primary outcome of interest will be rates of ER visit and readmission to hospital within 30 days of discharge compared to propensity score matched historical control patients. A power calculation suggests that 120 patients per group are necessary explaining why the intervention group will be 120 patients. We chose to compare our intervention to a matched group of 240 individuals from historical data which already captures follows patients 30 days after surgery but is limited in its Telehealth intervention. Duration of the study is 12 months.
To evaluate the feasibility of a pragmatic, large scale, comparative effectiveness, randomized evaluation of patient experience of intravenous propofol versus inhaled volatile anesthesia.
This study was performed to analyze the postoperative analgesic effects of the paravertebral block (PVB) and Mid-Point Transverse Process Pleura (MTP) block after a unilateral mastectomy surgery. This study included 64 women aged 18-65 years, American Society of Anesthesiologists score I-III, who were scheduled for unilateral simple mastectomy operation due to breast cancer. Patients were randomly assigned to Group 1 (Patients undergoing PVB) or Group 2 (Patients undergoing MTP block) for a ratio of 1:1, including 32 patients each, using a computer-generated table of random numbers and concealed sealed opaque envelopes. Patients were placed in the prone position. The linear ultrasound probe was fixed to the T3-T4 vertebra level. The skin and subcutaneous tissue were anaesthetized with 2% lidocaine, then 22 gauge 100 mm needle was led in a cranial-cephalic direction to the paravertebral gap. Trapezius, rhomboid, erector spinae muscles were crossed by seeing the tip of the needle. Transverse processes were reached and the intercostal muscles were passed. When the needle reached the paravertebral level in Group 1, and the midpoint level between the transverse process and pleura in Group 2, it was observed that there was no blood or air by aspiration. Then, the needle location was confirmed with 0.5-1 mL of saline, and a 20 mL of 0.25% bupivacaine was applied. Thirty minutes after block application, the sensorial block level was evaluated by pinprick test at the midclavicular line, and the blocked dermatome area was recorded as front and back. Complications developed during the process (such as hypotension, vascular injury, local anaesthetic toxicity) were recorded.Routine general anesthesia protocol was performed to all patients.At the end of the surgery, neuromuscular block antagonization was performed with 4 mg/kg sugammadex. All of the patients were extubated and taken to the postanesthetic care unit (PACU). In the PACU, a patient-controlled analgesia device (PCA) containing fentanyl was administered. Time to the first request for analgesia, postoperative fentanyl consumption, and VAS score values at rest and in motion at postoperative 1, 4, 8, 12, 16, 20 and 24 hours, the duration of block implementation and the duration of surgery were recorded.
A monocenter observational study will be started to investigate postoperative cognitive dysfunction 5 years after minimally invasive cardiac surgery. Postoperative cognitive dysfunction will be evaluated in three groups: an endoscopic-CABG group (endo-CABG), a PCI (Percutaneous Coronary Intervention) group and a healthy control group. It is hypothesized that the endo-CABG group will show a stronger postoperative cognitive dysfunction compared to the PCI group and the healthy control group.
Comparison of nutritional and early surgical outcome between early and delayed oral feeding after esophagectomy for esophageal cancer
Laparoscopic appendectomy causes postoperative pain. The primary objective of this prospective randomized controlled study is to compare the effect of ultrasound (US)-guided quadratus lumborum block (QLB) on 24-hour cumulative opioid requirements with transversus abdominis plane (TAP) block.
Radical cystectomy is the gold standard treatment for muscle invasive bladder cancer as well as some T1 and non-invasive disease. It is a major operation with significant perioperative morbidity and complications. Pain is one of the most important complications to be managed. Regional blocks as a part of multi-modal analgesia are considered main strategies of Enhanced Recovery after Surgery (ERAS) decreasing post-operative complications including post-operative pain and post-operative hospital stay. They also have an upper hand over systemic intravenous opioids decreasing the risk for post-operative delirium specially in old age patients. Thoracic paravertebral plane block (TPVPB), intra muscular quadratus lumborum plane block (QLPB) and erector spinae plane block (ESPB) are among these regional anesthesia techniques for pain management. Erector spinae plane block is an emerging block, with low risk and more feasibility, but efficacy hasn't been compared to quadratus lumborum and paravertebral plane blocks altogether in radical cystectomy surgeries. All these blocks are effective in reducing postoperative pain and the need of analgesia in radical cystectomy surgery; this is a comparative study between the three blocks in this population.
