Active clinical trials for "Pain, Postoperative"

A comparison study was performed between laparoscopic appendectomy and open appendectomy in acute setting in tertiary hospital to access the outcome of postoperative pain and hospital stay. As the popularity of laparoscopic appendectomy has failed in major tertiary hospital due to huge amount of patient load in which open appendectomy was performed.This study was performed to prove that outcome of laparoscopic appendectomy are far better than open appendectomy and to increase the use of laparoscopic surgery in acute settings

The aim of this randomized clinical trial was to compare the incidence, intensity and duration of postoperative pain following the removal of root canal obturation materials canals using rotary (ProTaper Universal or Hyflex EDM) or reciprocating file (Reciproc Blue or WaveOne Gold) systems. The null hypothesis tested was that there is no difference in postoperative pain following the retreatment procedure between the four systems used.

Compare pain response following microsurgical conventional flap approach using Piezosurgery versus flapless approach for esthetic crown lengthening in management of patients with short clinical crowns in the upper anterior region.

Adenotonsillectomy surgery in paediatrics is commonly managed as an ambulatory surgery. This may be attributed to the use of the electro-dissection surgical technique that decreases the incidence of immediate postoperative haemorrhage. However, the use of the electro-cautery technique increases postoperative inflammation. This study aimed to compare the glossopharyngeal nerve block using the blind technique with the use of the ultrasound guidance Primary: FLACC score in the two groups 0,2,4,6 h after surgery at rest and with swallowing Secondary: need to analgesics, the difficulty of the technique, time consumption, recovery time, surgeon satisfaction, parents satisfaction, staff nurse satisfaction, anaesthetist self-confidence

This is a single-center, randomized and prospective trial of all patients undergoing S-ICD implantation. Subjects will only be eligible for this study if they are ≥ 18 years of age and eligible to undergo S-ICD implant at Mount Sinai Morningside Hospital. They will be randomized to receive either surgical infiltration of local anesthetic or truncal blocks. Intraoperative and postoperative data will be collected including total opioid use, pain scores postprocedure, total postoperative narcotic need and length of stay.

The process of non-surgical retreatment includes removing the previous root canal filling materials, disinfecting and sealing the root canal system to prevent re-infection. Gutta-percha is the most common root canal filling material used with various types of sealers. To remove gutta-percha, solvent has been suggested because of its ability to dissolve gutta-percha. The new formula, under the brand name, GuttaClear, has been investigated for its comparable dissolving ability and lower cytotoxicity when compared with others that are currently used. However, no information is currently available of GuttaClear solvent concerning postoperative pain. Therefore, the present study will evaluate postoperative pain after non-surgical retreatment cases using GuttaClear as a solvent compared with no solvent used. Sixty participants are chosen and distributed into 2 groups, randomly. After the procedures, participants will receive the questionnaires about postoperative pain and the amount of medication intake. Both will be recorded at six time periods: (1) immediately after procedure; (2) 6 hours after procedure; (3) 12 hours after procedure; (4) 24 hours after procedure; (5) 48 hours after procedure and (6) 72 hours after procedure.

A placebo-controlled and double-blind study is planned according to current legislation and ICH GCP guidelines with 80 patients at Nordland Hospital, Bodø. Fifty percent are randomized to receive bupivacaine 5 mg / ml on the gauze swabs used to stop the bleeding after tonsillectomy, and 50% receive 0.9% sodium chloride. Pain at rest and pain when swallowing according to numerical rating scale (0-10), as well as the presence of the following symptoms (yes / no): nausea, vomiting, food intake, bleeding, fever, need for extra painkillers in the form of morphine or similar will be registered 1, 2, 3, 4, 5, 6 hours and 1, 2 4 and 6 days after the operation. Differences are analyzed with "mixed models" statistics and the results will be published in a peer-based journal.

The purpose if to find out if analgesia with bilateral ultrasound-guided Tranversus Abdominis Plane (TAP) block with Ropivacaine 0.5% is better than analgesia with local infiltration of trochar sites with Ropivacaine 0.5% in patients undergoing laparoscopic cholecystectomy. Our hypothesis is that in laparoscopic cholecystectomy, bilateral TAP blocks will reduce postoperative pain scores when compared to conventional postoperative pain control with local infiltration of trochar insertion sites.

Pain after tonsillectomy can be severe and last ten days. Various new surgical instruments have been developed over the years in an attempt to reduce postoperative pain with mixed results and increased costs; no single tonsillectomy technique is superior to the rest. Patients are discharged to home usually on the day of surgery and often suffer significant pain and nausea. Pain medication is often prescribed which can cause nausea, vomiting and constipation. Children in pain are reluctant to take in fluids and may require intravenous hydration at an emergency department. "Battlefield acupuncture " has been recently developed by the US Air Force and is now being used in Iraq and Afghanistan on wounded warriors suffering severe acute pain from trauma. This protocol consists of five acupuncture points on the outer ear. A recent study has demonstrated decreased pain and agitation in children undergoing ear tube insertion. Ear tube patients have mild discomfort compared to tonsillectomy patients and are able to attend school the next day. The investigators have been encouraged by the benefits of acupuncture during surgery for ear tube patients and also wounded warriors recovering from their injuries. These findings motivated us to see if acupuncture during tonsillectomy surgery would result in less pain and nausea.

The purpose of this study is to compare two methods of postoperative pain management in patients undergoing total knee replacement.
