Active clinical trials for "Pain, Postoperative"

HYPOTHESIS HAL- RAR causes a lower immediate postoperative pain compared with excision hemorrhoidectomy. HAL - RAR achieves similar immediate and long term results compared to the excision hemorrhoidectomy in the control of hemorrhoidal symptoms. The complication rate of HAL- RAR is low and similar to excision hemorrhoidectomy. OBJECTIVES Compare postoperative pain of both techniques. Assess the short and long-term control of hemorrhoidal symptoms by HAL- RAR technique, and compare the results with those of the excision hemorrhoidectomy. Evaluate and compare the rate of complications of both techniques. Assess the quality of life of patients before and after treatment.

The investigators believe sufficient spread to all nerves within the adductor canal-and thereby sufficient analgesia-can only be obtained by bolus injections and not by continuous infusions via a catheter. The aim of the study is to investigate whether an adductor canal block performed as repeated intermittent boluses provides superior pain relief to continuous infusion. The investigators hypothesize that adductor canal block performed as intermittent boluses via a catheter will reduce morphine consumption and pain as well as enhance ambulation and muscle strength compared with continuous infusion.

Aim The aim of this clinical study was to evaluate the influence of the instrumentation techniques on the incidence and intensity of postoperative pain in single-visit root canal treatment. Methodology Ninety patients with single root/canal and non-vital pulps were included. The patients were assigned into 3 groups according to root canal instrumentation technique used; the modified step-back (stainless-steel hand files, HF), reciprocal (WaveOne, WO), and rotational (ProTaper Next, PTN). Root canal treatment was carried out in a single visit and the severity of postoperative pain was assessed by 4-point pain intensity scale. All the participants were called through phone at 12, 24 and 48 h to obtain the pain scores. Data were analyzed by the Kruskal-Wallis test.

To extend the duration of peripheral nerve blockade after major foot and ankle surgery the investigators randomize the postoperative treatment with either perineurial sciatic nerve blocks with 0.5% Bupivacaine-Epinephrine with or without Dexamethasone.

We will enroll patients submitted to feet elective orthopaedic surgery that require analgesia through continuous peripheral nerve block (CNPB) of the sciatic nerve. All catheters will be placed by anaesthesiologists experienced in ultrasound in prone positioning. The patients will be randomized in two groups with technique of sealed envelopes. In the tibial -peroneal nerve (TPN) group we will position the catheter within the confluence of peroneal and tibial nerve. In the tibial nerve (TN) group we will proceed , previous local anaesthesia, to insert a catheter medially to tibial branch of the sciatic nerve according to in plane approach. We will analyze A: the difference in consumption of local anesthetic in the two different groups B: the difference of "insensate limb" in the post-operative home as described by Ilfeld(inability to perceive the sense of touch throughout the area of distribution of the sciatic nerve) C: rate of foot drop D: numeric rate scale (NRS) for pain assessment, rate of dislodgment of the catheters, patient satisfaction, need for intervention by the anesthesiologist after discharge.

A total of 86 patients underwent total hysterectomy. Three of them refused randomization, 34 were randomly assigned to undergo to laparoendoscopic single-site surgery (LESS) and 34 to undergo micro-laparoscopy (M-LPS).Laparoscopic hysterectomy can be safely performed by M-LPS and LESS.

A double blinded randomised control trial comparing the differences between laparoscopic single incision versus multiple port bariatric surgery in morbidly obese patients (BMI>35). Single incision surgery is a new minimally invasive surgical technique requiring the surgeon to operate through one small single incision and is virtually scarless. The traditional laparoscopic approach to abdominal surgery is through multiple small incisions (4-7 ports) across the whole abdomen. This study seeks to identify the risks, benefits and costs of the adjustable gastric band insertion via single incision and multiple incision within the morbidly obese patient group.

This is a three armed prospective randomized trial that will compare two different surgical techniques for reconstruction of the abdominal wall diastasis with a conservative treatment procedure. The study hypothesis: Which surgical approach provides the safest and best long term results for patients with abdominal wall diastasis either the insertion of net alternative with a double row suture or exercise alone?

The purpose of this study is to determine whether the use of triple antibiotic paste as intracanal medication with an anti-inflammatory drug, compared to a calcium hydroxide will reduce postoperative pain and intracanal bacteria or not in patients with asymptomatic necrotic teeth.

Analgesia following surgery associates different intra-venous or oral analgesic drugs and sometimes opioids. To reduce opioid consumption, loco-regional anaesthesia might be administered as a complement. In the specific context of caesarean sections, pain control is mandatory to enable the mother to take care of her offspring and shorten their hospital stay. This intervention is mainly performed under neuraxial anaesthesia (spinal or epidural), enabling the injection of morphine in the subdural or epidural space, as part of a multimodal analgesia regimen. Studies have evaluated continuous wound infiltration catheters (CIC) and ultrasound-guided (UGD) transabdominis plane (TAP) block, and both techniques and both techniques reduce postoperative morphine consumption. Recent studies have compared the two techniques and found conflicting results. Furthermore, they did not consider caesarean section performed under epidural analgesia, with a different neuraxial injection site, neither did they compared pain after postoperative day 2. Consequently, the aim of this study was to compare resting and standing pain up to postoperative day 3 after caesarean section performed under spinal or epidural anaesthesia and receiving either USG-TAP block or CIC. Baseline hypothesis was that the continuous infiltration provided a better analgesia at day 2.
