Pain, Post-operative

The goal of this clinical trial is to evaluate whether different positioning in the operating room during removal of laparoscopic surgical gas differs in post-surgery shoulder pain. An additional goal of this study is to evaluate whether positions change other post-surgery metrics such as bloating, time to passing gas, nausea and vomiting, and time to oral intake. Researchers will compare Trendelenburg positioning where your head is tilted down to supine (level or flat) positioning during removal of surgical gas. Participants will be asked to complete brief surveys at 24 and 72-hours post-surgery.

This trial is being completed to compare two commonly used options to treat pain after discharge from surgery. Participants that undergo tonsil removal, gallbladder removal, and knee scope will be eligible to enroll. Eligible participants will be randomized to prescription of 1 of 2 groups of medications (Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) plus acetaminophen or low dose opioids with the NSAIDs plus acetaminophen. The key question the study seeks to answer is which option will have the best outcomes and with the fewest side effects?

In 230 patients undergoing mastectomy, the investigators will compare opioid-free anesthesia (OFA) versus conventional opioid-based anesthesia in terms of chronic pain. The enrolled patients will be randomly assigned into two groups with 1:1 ratio. Chronic pain will be evaluated at 1 year after mastectomy based on the Breast Cancer Pain Questionnaire (BCPQ). Baseline pain sensitivity test and psychologic evaluation will be done before operation.

The goal of this randomized clinical trial is to compare patient-reported pain and oral health-related quality of life during the first postoperative week following extraction and bone graft surgery in patients who received preemptive ibuprofen versus placebo. Participants will receive ibuprofen 600mg or placebo by mouth with water 1 hour prior to extraction and bone graft surgery. The primary question it aims to answer is: • Does preemptive ibuprofen have an effect on postoperative pain 1 hour following extraction and bone graft surgery compared to placebo? Secondary questions are: * Does preemptive ibuprofen have an effect on pain during the first 3 postoperative hours and 7 postoperative days following extraction and bone graft surgery compared to placebo? * Does preemptive ibuprofen have an effect on oral health-related quality of life during the 7 postoperative days following extraction and bone graft surgery compared to placebo?
