Dynamic hip kinematics during recreational classical ballet and hula dance after total hip arthroplasty: two case reports

The in vivo assessment of the three-dimensional kinematics of the hip during dance activities in patients after total hip arthroplasty has not been previously reported. We evaluated the replaced hip kinematics du...

Bupivacaine infiltration in children for postoperative analgesia after tonsillectomy: A randomised controlled study

BACKGROUND Adenotonsillectomy is a frequently performed procedure in paediatric day-case surgery. Postoperative pain can be significant and standard analgesia protocols are often insufficient. OBJECTIVE Our primary objective was to investigate if infiltration of the peritonsillar space with bupivacaine would reduce the need for postoperative opioids compared with pre-emptive intravenous tramadol. DESIGN A prospective, double-blind, randomised controlled trial. SETTING Ambulatory surgical day care centre, University Hospitals of Leuven, Belgium, from January 2012 to September 2016. PATIENTS Two hundred children, between 4 and 10 years old, undergoing elective adenotonsillectomy were included in the study. INTERVENTION Children were randomly allocated to receive either a bolus of 3 mg kg−1 intravenous tramadol or infiltration of the tonsillar lodge with 5-ml bupivacaine 0.25%. Reasons for exclusion were American Society of Anesthesiologists classification greater than 2, allergies to the investigated products, psychomotor retardation, bleeding disorders and lack of proficiency in Flemish. MAIN OUTCOME MEASURES The primary endpoint was the number of children in need of piritramide postoperatively. Secondary outcomes included the cumulative dose of postoperative piritramide, pain scores and the incidence of postoperative nausea and vomiting during the first 24 postoperative hours, time to discharge and adverse effects. RESULTS The proportion of children in need of postoperative piritramide was significantly lower in the tramadol group than in children with peritonsillar infiltration (57 vs. 81%, P

Epidemiology and incidence of severe respiratory critical events in ear, nose and throat surgery in children in Europe: A prospective multicentre observational study

BACKGROUND Ear, nose and throat (ENT) surgery, the most frequently performed surgical procedure in children, is a strong predictor for peri-operative respiratory complications. However, there is no clear information about peri-operative respiratory severe critical events (SCEs) associated with anaesthesia management of ENT children in Europe. OBJECTIVE To characterise the epidemiology and incidence of respiratory SCEs during and following ENT surgery in Europe and to identify the risk factors for their occurrence. DESIGN A secondary analysis of the Anaesthesia PRactice In Children Observational Trial, a prospective observational multicentre cohort trial. SETTING The study included 261 centres across 33 European countries and took place over a consecutive 2-week recruitment period between April 2014 and January 2015. PATIENTS We extracted data from 5592 ENT surgical procedures that were performed on 5572 children aged 6.0 (3.6) years (mean (SD)) from the surgical database and compared these with data from 15 952 non-ENT surgical children aged 6.7 (4.8) years. MAIN OUTCOME MEASURES The primary outcome was the incidence of respiratory SCEs (laryngospasm, bronchospasm and new onset of postoperative stridor). Secondary outcomes were the differences in epidemiology between ENT children and non-ENT surgical children and the risk factors for the occurrence of respiratory SCEs. RESULTS The incidence (95% confidence interval) of any respiratory SCE (laryngospasm, bronchospasm and postoperative stridor) was 3.93% (3.46 to 4.48) and was significantly higher than that observed in non-ENT surgical children [2.61% (2.37 to 2.87)], with a relative risk of 1.51 (1.28 to 1.77), P less than 0.0001. Younger age (14% decrease in critical events by increasing year, P

A comparison of the analgesic efficacy of local infiltration analgesia vs. intrathecal morphine after total knee replacement: A randomised controlled trial

BACKGROUND Local infiltration analgesia (LIA) is an effective pain management technique following total knee arthroplasty (TKA). OBJECTIVE To investigate if LIA provides better analgesia for patients undergoing unilateral TKA than intrathecal morphine. DESIGN Randomised controlled trial. SETTING Single tertiary referral centre. PATIENTS Consecutive American Society of Anesthesiologists Physical Status I to III patients scheduled to undergo unilateral TKA were randomised to two groups. INTERVENTION The control group received spinal anaesthesia with intrathecal bupivacaine and preservative-free morphine 0.3 mg. The intervention group received opioid-free spinal anaesthesia with bupivacaine, followed by intra-operative infiltration of the knee with levobupivacaine 2 mg kg−1 and adrenaline 0.5 mg diluted to a volume of 100 ml with 0.9% saline. An intra-articular catheter was placed during surgery and used to give a bolus of 15 ml of levobupivacaine 0.5% on the morning of the first postoperative day. MAIN OUTCOME MEASURES Visual analogue scale (VAS) scores for pain were assessed repeatedly for 48 h postoperatively, at rest and on passive knee flexion to 30°. The primary outcome was VAS scores for pain at rest and on movement at 24 postoperative hours. Secondary outcomes were VAS scores at rest and on movement at 2, 6, 12 and 48 postoperative hours, opioid consumption, degree of active flexion of operative knee achieved in the first 48 h and the incidence of opioid-related side effects. RESULTS Forty three patients completed the study. Mean (± SD) VAS scores for pain at 24 h were lower in the intervention group than the control group at rest; 16.43 (± 20.3) vs. 37.2 (± 33.6), (P = 0.029). VAS scores for pain at 24 h on movement were also lower in the intervention group vs. the control group; 39.1 (± 22.8) vs. 57.0 (± 30.9), (P = 0.037). VAS scores were also lower on movement; 25.9 (± 16.8) vs. 40.5 (± 24.0), (P = 0.028) at 48 h. CONCLUSION We conclude that LIA conferred superior analgesia compared with intrathecal morphine 0.3 mg at 24 and 48 h following TKA. TRIAL REGISTRATION Clinicaltrials.gov identifier: NCT01312415.
