Active clinical trials for "Pain, Postoperative"

This prospective, double-blinded, randomized controlled study evaluates the effects of peripheral nerve blocks with and without local infiltration analgesia for postoperative pain management after primary total knee arthroplasty. There are no any studies that show the demand for local infiltration analgesia when together peripheral nerve blocks are performed. Patients undergoing primary total knee arthroplasty will be randomly assigned to receive local infiltration analgesia with or without (placebo group) local anesthetic. All patients will receive peripheral nerve blocks for postoperative analgesia: femoral triangle and distal adductor canal blocks. Comparison of these two groups of patients will be based on the effects on postoperative pain control, the extent of motor blockade, the ability of early leg motion and ambulation, patients satisfaction rates over the time of clinical recovery. Consequently, the investigators hypothesized that peripheral nerve blocks (femoral triangle and distal adductor canal blocks) with and without local infiltration analgesia provide similar postoperative pain relieving effects and the ability of early mobilization after total knee arthroplasty.

2QR-complex is a patented molecule extracted from Aloe vera barbadensis leaves that blocks the adhesion of pathogenic microbes to human epithelial cells and tissues [9]. Anti-adhesion therapy such as 2QR-complex has been suggested as an alternative to antibiotics in the treatment of bacterial infections. 2QR-complex based products have already shown comparable efficacy to antibiotics in treating mucosal infections such as bacterial vaginosis. In the present study we aim to assess the efficacy of 2QR-complex in pain relief and promotion of anal wound healing after anal surgery. We presumed that anal discomfort and prolonged healing after surgery for anal fissure, fistula, and hemorrhoids may in part be due to contamination of the wound with fecal bacteria that colonize at the surgical site. Therefore, we assumed that the use of topical anti-adhesive 2QR-complex-based product may serve to minimize this negative impact on wound healing.

This study examine the effect of Pericapsular Nerve Group (PENG) Block on analgesia after elective hip arthroplasty. Half of participants will receive a PENG Block with local anesthetic, while the other half will receive a PENG Block with a placebo.

Transsphenoidal surgery is considered safe and effective and is currently the procedure of choice for the removal of intrasellar lesions. Direct transnasal access to the sphenoid sinus, without the need for detachment of the nasal septum, provides less postoperative morbidity compared to traditional methods. Sphenopalatine ganglion block is known for its efficacy in otorhinolaryngological surgeries in which the sinuses are approached by transnasal endoscopy, as an important part of postoperative analgesia. However, in a neurosurgical environment, specifically in the treatment of tumors of the sella turcica, the use of the blockade of the referred ganglion to produce postoperative analgesia has been used in a scarce way in the literature. The primary objective of the study is to verify whether blocking the sphenopalatine nerve ganglion in the nasopharynx posterior wall provides better postoperative pain control in surgeries with nasal access for transsphenoidal approach, compared to the placebo group. As secondary objectives, the investigators will observe the consumption of opioids in the intraoperative period, in addition to the incidence of nausea, vomiting and postoperative headache also within 24 hours. Forty patients with physical status P1, P2 or P3 will be prospectively analyzed by the American Society of Anesthesiology (ASA) to undergo microsurgery for tumors with a sellar and / or suprasellar location, with transsphenoidal access, in patients with an age range between 18 and 64 years old, including men and women.

the purpose of this study is to compare opioid consumption in morphine equivalents between the groups that received postoperative analgesia with intrathecal morphine versus US guided QL blocks versus US guided QL catheters

The primary objective of this study is to evaluate the analgesic efficacy of Dexmedetomidine Transdermal System (DMTS), compared with placebo, in participants following abdominoplasty.

extrusion of infected dentin into the periapical tissue has been suggested as a major source of pain after endodontic treatment. Although debris extrusion is an inevitable finding even when instrumentation is limited to the confines of the canal, different armamentarium seem to be associated with different amounts of debris extrusion. Studies on the effect of various rotary files on post-endodontic pain are very few and have yielded conflicting results with some favoring full-sequence and others leaning towards reciprocal rotary systems. This study aims at assessing the intensity of post-endodontic pain following two different rotary systems, Reciproc and race. Methods: in this single-blind, parallel-grouped randomized clinical trial a total of 150 otherwise healthy patients aged between 20 to 50 years old with a pulpal status of irreversible pulpitis for one tooth in the upper or lower molar region were analyzed. A clinician performed the endodontic treatment in two groups, a group instrumented using race and a third group with instrumentation performed using Reciproc rotary systems.

This study will investigate the effect of three types of wound infiltration on post Cesarean opioid analgesia consumption when used in conjunction with an opioid free postoperative analgesia pathway.

This study showed the difference in postoperative pain between the groups that performed surgery with the low-pressure pneumoperitoneum and the group that performed surgery in the standard-pressure pneumoperitoneum when robotic single-hole cholecystectomy was performed. The primary purpose of the study was to compare the differences in the visual analog scale (VAS) between the two groups and to demonstrate the effectiveness of pain relief after surgery. Secondly, the effect of the low-pressure pneumoperitoneum on the patient's postoperative recovery and outcome was compared with the control group by comparing the length of stay, operation time, and postoperative complications.

Since the original publication on the erector spinae plane (ESP) block in 2016, the technique of the ESP block has evolved significantly in the last few years. Current reports suggest that the ESP block provides adequate analgesia in thoracic and abdominal sites in a post-surgical and chronic pain patient. However, there were still inconsistencies and unclear spread of local anesthetics in ultrasound guide ESP block. This study focusing on the spread of local anesthetic in ESP block under ultrasound and fluoroscopy and possible mechanisms of action.
