Filter by:This study compares the tow technique of continues adductor canal block for total knee replacement surgery. Half participants will receive catheterization at the entrance of the adductor canal, while the other half will receive catheterization at the middle point of the adductor canal.
This retrospective observational study compare ultrasound-guided plane and landmark-based superficial cervical plexus block
For superficial surgery of anteromedial and posteromedial surfaces of the upper arm, the medial brachial cutaneous nerve (MBCN) and the intercostobrachial nerve (ICBN) must be selectively blocked, in addition to an axillary brachial plexus block. We compared efficacy of ultrasound-guided (USG) versus conventional block of the MBCN and the ICBN.
To see if there is there any difference in the treatment outcomes/results such as changes in pain intensity in patients with myofascial pain who have been treated with trigger point injections or twin block?
In this study the investigators would like to show that when patients undergo upper limb surgery under supraclavicular brachial plexus block, additional blocking of the Intercostobrachial Nerve Block (ICBN) does not affect the incidence or course of tourniquet pain.
Moderate to severe postoperative pain often influence patients quality of recovery after hepatectomy. Systemic opioids given with patient-controlled analgesia has been used after hepatectomy in many medical center, but the analgesic effect can be limited and undesirable side effects may bring about negative effects on patients recovery. Regional block has been proved to improve patients postoperative recovery in many kinds of surgeries. The investigators therefore designed a prospective, randomized, subject and assessor blinded, parallel-group, placebo controlled study to test the hypothesis that continuous right thoracic paravertebral block increase patients quality of recovery score on the 7th postoperative day after hepatectomy in patients receiving i.v. patient-controlled analgesia (PCA) with morphine.
The classical transmuscular qudratus lumborum block(TMQLB) described by Borglum aims to provide lower thoracic paravertebral space(PVS) and sympathetic blockade by injecting local anesthetics between QL and PM muscle at the L3-L4 vertebral level using a transverse scan, posterior-anterior, in-plane approach. Recently, a paramedian sagittal oblique(TMQLB) approach has been introduced to facilitate cranial spread by injecting the local in a caudal to cranial direction. Currently, there are no data comparing the two techniques mentioned above with regards to extent of spread for PVS. Our objective is to investigate the extent of cranial dermatomal spread of TMQLB when equal dosage(ml/kg) of local anesthetic are injected with the transverse versus an modified paramedian sagittal approach for patients undergoing laparoscopic adrenalectomy. In addition, the investigators wish to compare the performance time, caudal dermatomal spread of TMQLB and postoperative analgesia effect.
INTRODUCTION: The axillary lymphadenectomy procedure is known to be associated with late postoperative complications, such as chronic pain and changes in shoulder mobility. Recently, several thoracic ultrasound guided interfascial blocks have been described, including serratus plane block. These blocks were associated with reduced postoperative pain scores in breast surgeries but were never evaluated in axillary dissection. The safety and feasibility of performing axillary dissection under local anesthesia and tumescent anesthesia associated with sedation has been demonstrated in case series, although it is not already the standard technique. DISCUSSION: This project aims to investigate the feasibility of the serratus plane block associated with intra-venous sedation in a prospective case series including 15 patients submitted to axillary dissection, by scoring patient and surgeon satisfaction with the technique, pain, quality of life with EORTC QLQ-C30 questionnaire, and quality of recovery with QoR-40 questionnaire in the first 30 postoperative days.
This study compares analgesic effect between two techniques of adductor canal nerve block after total knee arthroplasty. The first group of the patients will receive intraoperative adductor canal nerve block; and the other group post operative ultrasound guided adductor canal nerve block. Investigators will measure postoperative opioid consumption, pain management and rehabilitation goals.
In a randomized controlled crossover study design, ultrasound guided lumbar plexus blocks will be performed with and without the aid of a needle tip tracking (NTT) system. Specialists in anaesthesiology with average experience in ultrasound guided peripheral nerve block (PNB) techniques will perform the blocks. 27 volunteers will be included. The primary objective is to investigate the effect of the NTT system on performance time, as a measure for improved block performance. Secondary objectives are the effects of the NTT system on dexterity, peripheral nerve block characteristics, subjective experience, and peripheral block performance.
