ACB results in greater preservation of quadriceps muscle strength. Although we did not detect a significant reduction in fall risk when compared with FNB, based on the upper limit of the relative risk, it may very well be present. Further study is needed with a larger sample size.

Primary sclerosing cholangitis is a progressive cholestatic disease of unknown etiology leading to cirrhosis and liver failure. Several imaging modalities have been used to study this disease, including ultrasonography, computed tomography and hepatobiliary scintigraphy, but accurate diagnosis was found to be best made with endoscopic retrograde cholangiopancreatography or direct cholangiography. However, these 2 methods are invasive and may produce serious complications. Magnetic resonance cholangiopancreatography is a noninvasive imaging technique that has become very useful for diagnosing primary sclerosing cholangitis. Contrast enhanced magnetic resonance imaging provides pertinent information of extraductal abnormalities in addition to biliary ductal changes.

Background and objectivesThe major concern after inguinal hernioplasty is chronic postsurgical pain and impaired quality of life due to central sensitization. Preoperative, intraoperative, and postoperative pre-emptive analgesia using regional techniques may help prevent the development of central sensitization. This study evaluated the effect of regional anesthesia followed by continuous regional analgesia on postoperative pain and functional outcome following inguinal hernioplasty.MethodsSeventy-two consecutive patients scheduled to undergo open mesh inguinal hernioplasty were randomly allocated to one of three groups: subarachnoid block alone (group SAB), general anesthesia alone (group GA), or subarachnoid block combined with a continuous transverse abdominis plane block (group TAP). Pain and functional outcome was assessed before and 6 months following the surgery using the Core Outcome Measures Index score adapted for patients with hernia (COMI-hernia). During the first 72 hours postoperatively, pain was assessed at rest and during five different activities using the numerical rating scale.ResultsSix months following the surgery, the COMI-hernia score was lower in group TAP than in group GA or group SAB (0.54±0.41 vs 0.88±0.43 and 1.00±0.54, respectively; p<0.02). Pain at rest (p<0.02) and during activities (p<0.001) was lowest in group TAP during the first 72 hours postoperatively.ConclusionsA subarachnoid block combined with continuous postoperative analgesia via a transverse abdominis plane catheter provided better pain control and functional outcome 6 months following inguinal hernioplasty as well as better postoperative analgesia.Clinical trial registrationCTRI/2016/09/007238.

Introduction:Effective postoperative analgesia is imperative for orthopedic surgeries to enhance recovery and facilitate early ambulation. Various additives have been used as adjuvants with local anesthetics in peripheral nerve blocks to provide postoperative analgesia. The aim of this study is to compare the duration of postoperative analgesia with buprenorphine and dexamethasone when administered as an adjuvant during ultrasound-guided brachial plexus blocks.Methodology:Sixty adult patients undergoing various upper arm surgeries were recruited for the study after acquiring ethics committee clearance. They were randomized into two groups of thirty; Group B was given ultrasound-guided supraclavicular block with 10 ml 2% lignocaine with adrenaline and 15 ml 0.5% bupivacaine and 4 mg dexamethasone as adjuvant. Group B was given the same amount of local anesthetics with 0.3 mg buprenorphine as the adjuvant. The duration of postoperative analgesia and incidence of adverse events if any were noted.Results:Both groups were comparable in demographics, time for onset of sensory, and motor block. The duration of postoperative analgesia was 17.4 ± 3.4 h in the buprenorphine group and 18 ± 3.49 h in the dexamethasone group. None of the patients had significant adverse effects. A single dose of buprenorphine and dexamethasone administered perineurally can provide significant postoperative analgesia for upper limb surgeries.
