Active clinical trials for "Pain, Postoperative"

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.

Immediate pain reaction and return to work after TEP or Lichtenstein hernia repair have not been studied. In this multicenter trial the patients are allocated to surgery using TEP (n=50) or Lichtenstein (n=50) technique. Pain and return to work are recorded postoperatively up to one month. Immediate and late complications are also analyzed.

A significant component of pain experienced after abdominal surgery is related to incision of the abdominal wall and adequate analgesia can be a challenge. The ultrasound-guided (USG) quadratus lumborum block QLB was first described by Rafael Blanco in a presentation at ESRA 2007 at the XXVI Annual ESRA Congress in Valencia, Spain. Blanco described a potential space posterior to the abdominal wall muscles and lateral to the quadratus lumborum muscle where Local anesthetics can be injected. This technique provide analgesia after abdominal surgery due to spread of LA from its lumbar deposition cranially into the thoracic paravertebral space where lateral and anterior cutaneous branches from Th7 to L1 can be blocked . This was proved by Carney et al. who found traces of contrast agent in the TPVS following application of this block A novel USG QL block is the transmuscular approach which relies on clearly identifiable sonographic bony landmarks, Where the needle is advanced through the QL muscle, penetrating the ventral proper fascia of the QL muscle and LA is finally injected between the QL and Psoas major (PM) muscle. The transmuscular QL block does not result in redundant antero-lateral spread of the injectate. This may indicate that lower volumes of LA potentially can be used and yet provide extensive thoracolumbar anesthesia. This study was designed to compare the duration of analgesia provided by the original QLB and transmuscular QLB in patients undergoing surgical repair of unilateral inguinal hernia.

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.

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.

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?

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.
