Quality of Recovery-15 After Opioid-free Versus Opioid-based General Anesthesia in Major Urological Surgery

This randomized controlled trial evaluates postoperative quality of recovery assessed with the Quality of Recovery-15 questionnaire in adult patients undergoing elective major urological surgery under opioid-free versus opioid-based general anesthesia. Opioid-free anesthesia is a multimodal anesthetic technique that avoids intraoperative opioids by combining non-opioid analgesic and sympatholytic agents such as dexmedetomidine, ketamine, lidocaine, non-steroidal anti-inflammatory drugs, and regional analgesia. Opioid-based general anesthesia in this trial includes intraoperative remifentanil infusion. Participants will undergo elective urological surgery, including laparoscopic nephrectomy, robotic nephrectomy, laparoscopic prostatectomy, robotic prostatectomy, laparoscopic cystectomy, or robotic cystectomy. The primary objective is to compare patient-reported quality of recovery between the opioid-free anesthesia group and the remifentanil-based anesthesia group using the Quality of Recovery-15 questionnaire. QoR-15 will be assessed before surgery and on postoperative day 7. Secondary objectives include total postoperative oxycodone dose administered via patient-controlled analgesia during the first 24 hours after surgery, postoperative pain intensity measured using the Numeric Rating Scale at 1, 2, 6, 12, and 24 hours after surgery, incidence of postoperative nausea and vomiting, change in serum creatinine from baseline to postoperative day 1, change in white blood cell count from baseline to postoperative day 1, and the ratio of demanded to delivered PCA boluses. Pre-specified subgroup analyses will compare outcomes according to surgical procedure type: laparoscopic nephrectomy, robotic nephrectomy, laparoscopic prostatectomy, robotic prostatectomy, laparoscopic cystectomy, and robotic cystectomy. Subgroup-by-treatment interaction tests will be performed. Planned enrollment is approximately 600 patients, with 300 patients per treatment arm. The primary patient-reported recovery endpoint will be assessed on postoperative day 7, while analgesic, pain, and early postoperative safety outcomes will be assessed during the first 24 hours after surgery.

Opioid-free Anesthesia as an Alternative to General Anesthesia in Abdominal Surgery

Opioid-free anesthesia (OFA) is a multimodal technique that eliminates intraoperative opioids by combining dexmedetomidine, ketamine, lidocaine, NSAIDs, and regional analgesia. Growing evidence suggests OFA reduces postoperative opioid consumption, opioid-related adverse effects, and may have favorable oncological implications in cancer surgery. This randomized controlled trial compares OFA with opioid-based anesthesia (remifentanil) in patients undergoing elective urological surgery: laparoscopic nephrectomy, robotic nephrectomy, laparoscopic prostatectomy, robotic prostatectomy, laparoscopic cystectomy, and robotic cystectomy. The PRIMARY OBJECTIVE is to compare the total postoperative oxycodone dose (mg) administered via patient-controlled analgesia (PCA) during the first 24 hours after surgery between the OFA and remifentanil groups. SECONDARY OBJECTIVES include: postoperative pain intensity (NRS) at 1, 2, 6, 12, and 24 hours; incidence of postoperative nausea and vomiting (PONV); change in serum creatinine from baseline to postoperative day 1; change in white blood cell (WBC) count from baseline to postoperative day 1; and the ratio of demanded to delivered PCA boluses. PRE-SPECIFIED SUBGROUP ANALYSES will compare outcomes by surgical procedure type: laparoscopic nephrectomy, robotic nephrectomy, laparoscopic prostatectomy, robotic prostatectomy, laparoscopic cystectomy, and robotic cystectomy. Subgroup-by-treatment interaction tests will be performed and reported as forest plots. Planned enrollment: approximately 600 patients (300 per arm). Follow-up: 24 hours postoperatively.

Optimizing Pain Treatment in Children On Mechanical Ventilation

In this clinical trial, investigators want to learn more about using non-opioid pain medications for children with acute respiratory failure. Right now, doctors give these children opioids to help with pain while they are on the ventilator, but investigators don't know if this is the best way to manage their pain. Even with strong doses of opioids, more than 90% of these children still feel pain. Other pain medicines, like acetaminophen (also called Tylenol) and ketorolac (also called Toradol), are available but aren't commonly used because we don't know if they help. The goal of this clinical trial is to test if acetaminophen and/or ketorolac can improve pain control and reduce the need for stronger pain medications (opioids) in these children. To learn more about this, participants will be randomly placed in one of four study treatment groups. This means that a computer will decide by chance which group each participant is in, not the doctors running the study. Each group will receive a combination of intravenous acetaminophen, ketorolac or a harmless substance called a placebo. In this clinical trial, placebos help investigators see if the actual medications (acetaminophen and ketorolac) work better than something that doesn't contain medicine. By comparing participants who get the real medicine with those who get the placebo, investigators can find out if these medications effectively decrease pain.

Comparing the Safety and Effectiveness of Different Doses of Morphine Administered in Spinal Anethesia for Pain Relief After Hip Replacement Surgery

Pain management after total hip replacement is one of the most important aspects of postoperative care for patients and clinicians alike. One of the most common techniques used in anesthesia for this procedure is spinal anesthesia with concurrent administration of opioids into spinal sac. Addition of opioids not only prolongs the anesthesia but also provides pain relief after the procedure for a limited amount of time. Because of its unique chemical properties morphine provides the longest pain relief amongst currently known opioids lasting up to 24 hours. Unfortunately this beneficial effect is associated with both minor and serious adverse effects, most important of which is respiratory depression. To limit this potenitialy fatal adverse effect dosing of morphine must be very precise in order to balance advantages and risks. The aim of the study was to assess effectiveness and safety profile of different doses of morphine administered during spinal anesthesia for pain control.

The Effects of Transversalis Fascia Plane Block on Opioid Consumption in Patients Undergoing Hand-Assisted Laparoscopic Donor Nephrectomy: A Randomized Controlled Prospective Study

This study aims to evaluate whether a regional anesthesia technique called the transversalis fascia plane block (TFPB) can improve pain control after hand-assisted laparoscopic donor nephrectomy (HALDN), a minimally invasive surgery performed in living kidney donors. Although HALDN is less invasive than open surgery, patients often experience significant pain after the operation, mainly due to the surgical incisions in the lower abdomen and trocar entry sites. Poorly controlled pain can delay recovery and increase the need for opioid pain medications, which may cause side effects such as nausea, vomiting, itching, and sedation. The transversalis fascia plane block is an ultrasound-guided regional anesthesia technique in which a local anesthetic is injected into a specific tissue plane in the lower abdominal wall. This injection temporarily blocks pain signals from nerves supplying the lower abdomen and groin area. The technique has been shown to reduce pain and opioid use after various lower abdominal surgeries and is considered minimally invasive and safe when performed under ultrasound guidance. In this study, patients undergoing HALDN will be randomly assigned to one of two groups. One group will receive standard general anesthesia only, while the other group will receive general anesthesia plus a transversalis fascia plane block using a local anesthetic (bupivacaine). All patients will receive the same standard pain treatment after surgery, including paracetamol and patient-controlled morphine. The main goal of the study is to compare the amount of opioid pain medication used during the first 24 hours after surgery between the two groups. Secondary outcomes include pain scores measured using the Numeric Rating Scale (NRS), the frequency of opioid-related side effects, and patient satisfaction with pain control. The results of this study may help determine whether adding the transversalis fascia plane block to standard anesthesia can provide better pain relief, reduce opioid consumption, and improve comfort and recovery in living kidney donors.

Asleep Fiberoptic vs Direct Laryngoscopy Effect on Hemodynamic Stability Using Opioid Free Anesthesia Induction

The goal of this clinical trial is to compare blood pressure and heart rate between the fiberoptic and direct oral intubation using opioid free anesthesia induction. Secondary objectives include comparing the time needed for intubation and the incidence of postoperative sore throat, hoarseness, and upper airway trauma in adults aging between 18 to 55 years, scheduled for elective surgery under general anesthesia. The main question it aims to answer is: Does fiberoptic intubation cause less hemodynamic instability than direct oral intubation using opioid free anesthesia induction?

IPACK on Early Pain Scores After ACL Reconstruction

The goal of this clinical trial is to learn whether using an anesthetic technique called IPACK block will control pain after ACL reconstruction surgery. The main questions it aims to answer are: * if participants who receive the IPACK block prior to ACL reconstruction experience less pain after surgery and at 1 day after surgery * if participants who receive the IPACK block prior to ACL reconstruction require less short-term opioid use immediately after surgery and up to one week after surgery. Participants will be randomized 1:1 to 1 of 2 groups: Use of IPACK block during ACL reconstruction vs. placebo (a placebo is a look-alike substance that contains no active drug). Neither the participant nor the investigator will know which group the participants has been assigned to. Researchers will compare self-reported pain scores and short-term opioid use of all study participants.
