Tonsillectomy and risk of post-tonsillectomy haemorrhage - a protocol for a randomised clinical trial.

INTRODUCTION: Tonsillectomy is one of the most common procedures in the ear, nose and throat field, and 7.7% of the Danish population had undergone a tonsillectomy by the age 20 years in 2012. One feared complication is post-tonsillectomy haemorrhage (PTH), which in a Danish register-based study was found to increase from 3% in 1991 to 13% in 2012. PTH represents a significant risk and deaths are reported in the literature. The aim of the trial is to compare hot and cold haemostasis during tonsillectomy and assess, firstly, the risk of PTH and, secondly, the reported pain perception. METHODS: This is a single-centre, two-arm, interventional randomised controlled trial. The study targets patients > 12 years of age referred for tonsillectomy. Participants will have both tonsils removed; on one side cold haemostasis will be performed and on the other hot diathermia will secure haemostasis. The participants will subsequently receive three questionnaires in the course of a month concerning bleeding episodes and pain perception. Owing to the study design, patients and surgeons act as their own controls. CONCLUSIONS: The results of the study may guide future research and practice of tonsillectomy to reduce the risk of PTH.

Opioid consumption and non-opioid multimodal analgesic treatment in pain management trials after hip and knee arthroplasties: A meta-epidemiological study.

BACKGROUND: The leading principle in peri-operative pain management is multimodal analgesia, which reduces opioid requirements and associated adverse effects. Pragmatic pain trials should optimally test interventions in addition to multimodal non-opioid analgesics and interventions to ensure clinical relevance and baseline levels of opioid consumption that reflect clinical settings. We aimed to investigate opioid consumption and use of non-opioid analgesics administered adjunct to interventions in post-operative pain trials after total hip and knee arthroplasty. METHODS: A systematic literature search was conducted 7 January 2020 in The Cochrane Library's CENTRAL, PubMed, and EMBASE. Trials investigating analgesic interventions for post-operative pain in adults undergoing total hip or knee arthroplasty were included. The primary outcome was the aggregated median 0-24 h post-operative opioid consumption. Further, we assessed the use of paracetamol, non-steroidal anti-inflammatory drugs, gabapentinoids, high-dose glucocorticoids, local infiltration analgesia and nerve blocks administered as co-interventions equally to all participants. We assessed trends over time for all outcomes. RESULTS: Of 14,200 records, 570 trials were included. Median 0-24 h opioid consumption was 21 and 22 mg iv morphine equivalents in hip and knee arthroplasty trials, respectively. Meta-regression showed no overall linear correlation between opioid consumption and publication year. The use of multimodal non-opioid analgesia increased over time, though only 48% of trials published from 2010 to 2020 administered two or more non-opioid analgesics. Applying more non-opioid analgesics was associated with lower opioid consumption in intervention groups. CONCLUSION: Post-operative 0-24 h morphine consumption was median 21-22 mg. The demonstrated differences in non-opioid multimodal analgesic regimens between research and clinical settings, can potentially diminish the demonstrated opioid-sparing effects of trial interventions when such are implemented in a clinical context.

[Perilymphatic fistula in inner ear treated with blood patch].

Perilymphatic fistula (PLF) is a rare condition with a pathological communication between the inner ear and usually the middle ear, causing both cochlear and vestibular symptoms. PLF is typically treated with either a conservative approach or surgically with grafting. But a new treatment has been proposed: intratympanic injection of autologous blood, blood patch. This is a case report of a 21-year-old woman who presented herself with PLF and was successfully treated with blood patch.
