Active clinical trials for "Pain, Postoperative"

Many factors during laparascopic surgery leads to PONV (postoperative nausea and vomiting), such as C02 insufflations causing peritoneal stretch and irritation and type of anaesthesia given during surgery. The two anesthetic techniques used in bariatric surgery are gas anesthesia (Remifentanil TCI and Desfluran) and Total Intra Venous Anesthesia (TIVA) with propofol. There are studies which have shown a reduction in postoperative nausea and vomiting following TIVA, and there are publications showing no statistically significant difference. The aim of this study was to investigate the best anaesthetic approach for obese subjects, evaluating awakening time, postoperative nausea and pain. Our hypothesis was based on the fact that Propofol is a lipid-soluble anesthetic and therefore might have a prolonged effect in obese patients, leading to a longer awakening time along with postoperative nausea and vomiting. This hypothesis is also described earlier by obese patients have more depots (bulk fat) and also more fat surface making anaesthetics storage more easier, and also that the anesthetic will return into the circulation when the administration is stopped [18].

This is a two-part, Phase 2, multi-center, randomized, double-blind, placebo-controlled, parallel design study of CA-008 (vocacapsaicin) vs. placebo injected/instilled during an elective TKA.

To compare between caudal block and ultrasound guided Quadratus Lamborum block in reducing postoperative pain, opioid consumption, and recovery time following elective inguinal herniorraphy. The primary outcome: • to compare between caudal block and ultrasound guided quadratus lamborum block. The secondary outcome: duration of postoperative analgesia. incidence of postoperative complications.

The aim of this study is to assess the effect of ultrasound guided erector spinae block in control of the postoperative pain and the respiratory functions after laparoscopic cholecystectomy.

The over-prescription and overuse of opioid medications in the United States has recently been recognized as an epidemic. A new law in North Carolina (STOP Act) is aimed to limit opioid prescriptions following any surgical procedure including total hip (THA) and total knee arthroplasty (TKA). However, there is limited evidence regarding patient's pain and actual opioid consumption following THA and TKA that can be used by practitioners as guidance adapting to the new law. The purpose of this study is to investigate patient's pain and pain medication use in the perioperative period (0-6 weeks) following THA and TKA to establish a pain profile and thereby investigating risk factor for increased postoperative pain and opioid pain medication requirements. This study aims to stratify a predication model of postoperative pain and opioid medication requirement after THA and TKA to identify patients with a high propensity for pain, improve preoperative patient education on postoperative pain expectations, thereby helping practitioners implement new postoperative prescriptions limits for THA and TKA patient.

Comparison of the efficiency of oral Etoricoxib versus intravenous Fentanyl on post operative Pain in curettage under TIVA: A randomized controlled trial

Transversalis fascia plane block is a regional anesthesia technique described ten years ago. Its use for many indications has been identified by case reports in the literature. As the investigators have considered that transversalis fascia plane block could be efficacious for providing postoperative analgesia in the cesarean section, the investigators have implemented the application of this blockade into practice at the clinic. The main purpose of this study is to evaluate the analgesic effect of ultrasound-guided bilateral transversalis fascia plane block in cesarean section.

Phase 2, single center, randomized, double-blind, placebo-controlled, parallel design study of CA-008 vs. placebo in subjects undergoing an elective C-ABD under general anesthesia supplemented with a bupivacaine hydrochloride (HCl)transverse abdominis plane (TAP) block.

In an ideal endodontic treatment, maintenance of the original root canal morphology of the canal during root canal preparation, an ideal preparation and obturation is essential. Even if all stages are ideal, pain after endodontic treatment is a clinical condition that may occur after a few hours or several days. Post-operative pain after endodontic treatment is an undesirable condition which makes the clinician and the patient a distressing condition. Many clinical studies reported a 25-40% postoperative pain rate after endodontic treatment, which means that postoperative pain is a clinical symptom that should be considered for endodontist. The ProTaper Next files (Dentsply Tulsa Dental Specialties) operate in continuous rotary motion, and their center of mass or center of rotation is positioned off-center relative to the instrument's central axis of rotation. During rotation, the files of this design produce a mechanical wave of motion, which travels along the length of the working part of the instrument, minimizing the contact between the file and dentin. According to the manufacturer, the offset design of this instrument also improves debris removal and flexibility in the working part of the file. New heat treatment has been carried out on NiTi alloy, seeking to increase its flexibility and cyclic fatigue resistance. Recently, the Wave One Gold instrument, manufactured with a new thermal treatment called Gold treatment, was introduced on the market presenting some differences in design, size and taper compared to Wave One. Wave One Gold instrument has a parallelogram cross-sectional design, having two cutting edges, and consists of four instruments, 21/.06 (small), 25/07 (primary), 35/06 (medium) and 45/05 (large) while Wave One presents convex triangular cross-sectional design, besides larger size and taper. Reciproc blue (REB, VDW), a new-generation reciprocating single-file system, is the latest version of REC. Like the REC file, REB also has an S-shaped cross section, 2 cutting edges, and a noncutting tip. However, REB files are manufactured by altering the molecular structure through a new heat treatment in order to increase the cyclic fatigue resistance. This new heat treatment gives the file its blue color. It was reported that REB files have approximately 2 times higher cyclic fatigue resistance than REC files. In addition, REB files can also be relatively prebent to better access curved canals. However, the effect of Reciproc Blue, Protaper Next, Waveone Gold within preparation on the postoperative endodontic pain has not been investigated, yet. The aim of this prospective clinical trial was to clinically compare the incidence of postoperative pain after use of different nickel titanium file systems. The purpose of the present study was to evaluate the incidence of postoperative pain root canal preparation performed with Reciproc Blue, Protaper Next, Waveone Gold. The null hypothesis tested was that there is no difference in the incidence and severity of postoperative pain following with any of the 3 instruments.
