Post Operative Pain Management

This study aims to evaluate the effectiveness of Serratus Posterior Superior Intercostal Plane (SPSIP) block compared to Intercostal Nerve (ICN) block in terms of postoperative pain control, reduction of opioid analgesic consumption, minimization of postoperative respiratory complications, and increase patient satisfaction (using a 5-point Likert scale) in patients undergoing video-assisted thoracoscopic surgery (VATS).

This study is testing a new way to help manage pain after a double lung transplant. Instead of relying only on strong pain medicines like opioids, doctors will use a cold-therapy probe during surgery to help numb the nerves near the incision. Researchers want to see if this method can reduce the need for opioids and improve recovery.

The intervention in this study is to determine whether multiple applications of photobiostimulation with Nd-YAG laser improve wound healing following tooth extraction and alveolar ridge preservation. Investigators plan to assess the impact of laser treatment on wound healing by measuring salivary biomarkers, gingival wound size and surveying for the use of pain reduction and patient satisfaction. The intervention group will receive extraction and alveolar ridge preservation with Nd-YAG laser photobiostimulation on days 1, 3, and 7 following extraction and socket preservation, while the control group will receive the standard of care extraction and alveolar ridge preservation without the laser

This study aims to assess the impact of occlusal reduction on post-operative pain after single-visit root canal treatment in patients with necrotic pulps or previously initiated (accessed).

Patients undergoing spinal surgery require pain control medication after their surgery. Investigators have successfully used intravenous Methadone to manage pain after surgery. However, doctors in Canada do not have the intravenous form of Methadone to prescribe to their patients. The investigators in Canada propose a pilot trial to investigate whether Methadone administered rectally could be used to manage pain after spinal surgery. The main questions are: 1. Are investigators able to recruit participants for this trial and learn from this study to plan a larger trial? 2. Does Methadone administered rectally during surgery, reduce participants' pain intensity, use less pain medication, and have a better recovery after surgery? Investigators will compare Methadone to a placebo (a look-alike substance that contains no drug) to see if Methadone works to manage pain after surgery better than the usual pain management. Participants will: * receive either Methadone or placebo during surgery. * be asked some questions about their pain during days 1 to 3 after surgery * be contacted by phone to ask about their recovery At this time, the study aims to recruit 40 participants from St. Michael's Hospital, to learn whether it will be feasible to plan a larger study.
