Active clinical trials for "Pain, Postoperative"

This study aimed to evaluate pain after elective colorectal surgery and to identify risk factors for postoperative pain. Patients:All elective colorectal surgeries at the department of surgery, Umeå university Hospital, Umeå, Sweden from March 2013 to April 2017 Primary outcome:The primary outcome measurement is the numeric rating scale (NRS), graded from 0-10, on day of surgery, postoperative (POD) 1, 2, 3. The patients are questioned by nurses each morning on four postoperative days to score the maximum pain during the previous 24 hours using the NRS.

We want to investigate the correlation between the native femoral head and the implanted cup in Total hip arthroplasty. As second parameter to investigate we believe an oversized cup will cause groin pain. We want to find a cutoff value to predict groin pain after cup implementation in THA.

we will assess post operative pain after surgery of modified radical mastectomy at 12 and 24 hours post operatively on arm movement and on rest

Despite the major progress in anesthetic techniques, postoperative pain is still considered a major problem during practice. (1-3). Leading to many co-morbidities, one to two-thirds of patients will suffer postoperative pain. These co-morbidities can include; pulmonary complications, cardiac complications, and delirium(4). Numerous risk factors are associated with the emergence of postoperative pain, including; younger age, female sex, preoperative pain, and extensive surgical procedure. The severity of postoperative pain may vary among patients undergoing the same operation (5-10). Many techniques have been evolved to monitor nociception and predict postoperative pain intensity; one of the most recent techniques is the surgical pleth index (SPI)(11).SPI is a noninvasive dimensionless score; its value is obtained from heartbeat interval and pulse wave amplitude monitored by pulse oximetry probe.SPI reflects the sympathetic response of the patient to the surgical stimuli(12-13). It was reported that SPI is better than other parameters like heart rate and blood pressure for detecting the balance between nociceptor activation and analgesia(14-15), and its value is correlated with the severity of postoperative pain. SPI values range from 0 to 100, and higher values indicate strong surgical stimulus (16). SPI can be used as a guide for intraoperative analgesia; hence, it can be a valuable tool to assess the analgesic requirement and limit opioid consumption, both preoperative and postoperative(17). Several studies have been performed to predict the severity of postoperative pain using SPI in adults and children (16,18). It was also used successfully to expect a hemodynamic response to tracheal intubation and skin incision (19) and monitor nerve block success. (20). However, since SPI has emerged, the most sensitive cut-off value that correlates well with postoperative pain severity remained debatable. Recent studies reported a value of 30 as a cut-off value of SPI. (21). On the other hand, the time of measurement to rely on was debatable. Most studies recommended that a measure of SPI before recovery can be used. However, a more recent study suggested that SPI response to surgical incision is highly correlated with postoperative pain and opioid consumption (18). Based on these data, we hypothesized that both measurements are correlated with postoperative pain and aimed to test which measure is more correlated.

This project a European observational study on the incidence and characteristics of chronic post surgical pain (CPSP). Research Questions What is the incidence of chronic post surgical pain (CPSP) in Europe? What are the risk factors of chronic post surgical pain (CPSP) related to surgery, patient and anaesthesia management? What are the difference in incidence and risk factors in different European countries?

The purpose of this study is to establish reliability and validity of the Norwegian version of the Comfort behavioral scale.

A history and physical focused on clinical sequelae of breast implant rupture was completed by patients to assess long-term clinical sequelae of SKY0402 and its relation to the silicon shell.

External oblique and m-tapa blocks are routinely performed on patients undergoing laparoscopic cholecystectomy in our clinic. In this study, sensory block and regression rates will be investigated in patients who underwent block.

To adequately assess postoperative pain in the coronary artery bypass surgical population a multicentered retrospective chart review was carried out; the study utilized a nonexperimental comparative descriptive study design. The retrospective review was conducted over a six-month time frame, consisting of June 2017 through November 2017, at two hospitals within the same organization. The data collection process began in late December of 2017 and January of 2018. The assessment of postop pain was performed by using a standard 11-point numeric pain rating scale on post extubation day one and the day of discharge.

Our goal is to determine if liposomal bupivacaine compared to standard bupivacaine results in increased pain control and decreased narcotic pain medication use when used in TAP blocks prior to laparoscopic hysterectomies for benign indications.
