Active clinical trials for "Pain, Postoperative"

The perfusion index (PI) is the ratio of the pulsatile to the non-pulsatile blood flow in peripheral tissue. It represents a non-invasive measure of peripheral perfusion that can be continuously obtained from a pulse oximeter. This property explains the fact that it decreases with vasoconstriction and increases with vasodilatation. An increase in PI was proved to be an early indicator for the success of general and regional anaesthesia, which cause initial peripheral vasodilatation before the onset of anaesthetic effect. Whereas a failed increase in PI would suggest failure of anaesthesia. The PI has been reported to decrease when noxious stimulus was applied to anaesthetized volunteers. A recent study on critically ill non-intubated patients has demonstrated a good correlation between changes in PI and changes in Behavioral Pain Scale-non intubated values after a painful stimulus was applied. Despite the rising use of perfusion index in anaesthesia and intensive care, few studies have investigated its capability as a pain assessment tool, and to our knowledge, it has not been investigated in intubated critically ill patients yet.

Purpose: To explore effects of S-ketamine on postoperative pain and cognitive dysfunction after tibial fracture and orthopedic surgery. To evaluate and examine the incidence of adverse effects with the purpose of selecting the optimum dose.

The ultrasound-guided approach for the blockade of articular branches of femoral and obturator nerves, pericapsular nerve group (PENG) block, is an effective method for postoperative analgesia in hip surgeries.

Lidocaine is a drug that has multiple uses. One of these is that when intravenously administered it is effective in reducing post-operative pain. The aim of this study is to investigate the beneficial effects of intravenous lignocaine on reducing pain, nausea and vomiting after laparoscopic cholecystectomy. Also, by this research, we are aiming to find a suitable alternative analgesic.

Six years after, the authors will conduct the same analysis to check if there have been any improvements in the management of analgesic therapy after the measures taken according to the results of the previous study conducted in the same departments. During a single day work three committees, administering a questionnaire to patients or parents, will evaluate the adherence to international recommendations (JCI and WHO) in the management of analgesic therapy.

Hypospadias, seen in every 200-300 births, is one of the most common congenital anomalies of the penis and is defined as the urethral meatus being located in the ventral part of the penis instead of its normal place. The surgery of this anomaly is very painful in the postoperative period and requires long-term analgesia. Regional anesthesia methods combined with general anesthesia play an important role in providing effective and long-term postoperative pain control in pediatric penile surgery. These methods also reduce postoperative morbidity, enable early mobilization and significantly decrease the need for narcotic analgesics. The investigator's hypothesis is peripheral nerve blocks are superior to neuraxial blocks as the blocks provide longer-term analgesia and have fewer side effects.

INTRODUCTION Patients who will have obesity surgery have about %48 psychiatric illnesses like anxiety disorder. Studies which analyze the relationship between preoperative anxiety level and postoperative pain had reported conflicting results. The aim of this study is to search the relationship between preoperative anxiety level and postoperative pain and analgesic consumption in patients who had laparoscopic sleeve gastrectomy surgery. MATERIAL AND METHODS Our prospective double-blind study is planned to require 86 female patients aged between 18-65 years old, American Society of Anesthesiologists (ASA) I-II and Body mass index (BMI) ≥40 kg/m^2. Patients having a psychiatric or neurologic disease, brain damage, using psychiatric medications (antidepressants, anxiolytics) and chronic alcohol, known allergy to medications used in the study protocol, inability to provide informed consent will be excluded. Patients will be wanted to fill the Spielberger's State-Trait Anxiety Inventory the night before the surgery. The analgesic consumption of the patients will be recorded by evaluating the pain with Visual analog scale (VAS) and sedation status with Ramsay's sedation scale in the 1st, 4th, 12th and 24th hour of postoperative period. EXPECTATIONS AND SCIENTIFIC CONTRIBUTIONS More satisfying postoperative analgesia may be provided in this group of patients by determining correlation between preoperative anxiety level and postoperative pain and analgesic consumption in patients who had laparoscopic sleeve gastrectomy. Morbidity rate related with pain may be decreased and patient satisfaction may be increased.

Aim: Although regional anesthesia (RA) techniques are advantageous in the anesthetic management of obese patients (body mass index (BMI)≥30); their performances can still be associated with technical difficulties and greater failure rates. The aim of this study is to compare the performance properties and analgesic efficacy of ultrasound (US)-guided bilateral thoracic paravertebral blocks (TPVBs) in obese and non-obese patients. Material methods: After obtaining ethics committee approval; data of 82 patients, who underwent elective bilateral reduction mammaplasty under general anesthesia with adjunctive TPVB analgesia between December of 2016 and February of 2020, were reviewed. Patients were allocated into two groups with respect to their BMI scores (Group NO: BMI<30 and Group O: BMI≥30). Demographics, TPVB ideal US image visualization and performance times, needle tip visualisation and TPVB performance difficulties, number of needle maneuvers, surgical, anesthetic and analgesic follow-up parameters, incidence of postoperative nausea vomiting (PONV), sleep duration, length of postanesthesia care unit (PACU) and hospital stay, patient and surgeon satisfaction scores were all investigated and compared.

Rebound pain is a well-recognized phenomenon after the effects of a nerve block wear off. Severe rebound pain can happen after outpatient surgery, with patients often needing to come back to the hospital or use other health care resources. People who are younger, female or have more pain before surgery are at higher risk of having rebound pain. Bone surgeries and upper limb surgeries also increase the chances of having rebound pain after surgery. Patients who have a tourniquet used during leg surgery often have worse pain after surgery compared to patients who get surgery without the use of a tourniquet. Things that may reduce the chances of getting rebound pain are the use of nerve block catheters, certain additives in nerve blocks and using multiple types of pain killers before the block wears off. Using nerve block catheters can be expensive, so a targeted approach of giving these catheters to patients who have the highest chances of getting rebound pain may be the best way to allocate resources and help patients. The aim of this study is to create and test a risk model for severe rebound pain after lower limb surgery where patients are getting a sciatic nerve block.

In this study, it was aimed to investigate the analgesic efficacy of the preoperatively applied Transversus Abdominis Plane (TAP) Block in the management of acute appendicitis-related abdominal pain and post-appendectomy pain.
