(Ton)silly seasons? Do atmospheric conditions actually affect post-tonsillectomy secondary haemorrhage rates?

Abstract

The findings revealed no correlation between humidity, season, water vapour pressure and haemorrhage rates. Further research should use multi-site data to investigate the effect of air conditioning, humidification and climactic conditions between different regions in Australia.

Post-tonsillectomy haemorrhage in Australia—a multivariable analysis of risk factors

“…Whilst numerous studies have been conducted on PTH, there is still significant variation in the reported rates of secondary PTH (5,8,10,14,28,29). The secondary PTH rate in this study is 6.9%, which is consistent with reported rates in literature, with Australian studies reporting PTH rates ranging from 2.0% to 7.7% (18,21,22). A review of 63 studies by Blakley et al concluded that the maximum acceptable PTH rate is 13.9% (29).…”

“…However, evidence for the role of post-operative infection as a cause for secondary PTH remains inconclusive (26,27,48,49). Other studies, including the only Australian study analyzing seasonal variation in PTH rates, did not show any difference between seasonal PTH rates (18,50,51). Although most of these studies utilise univariate analyses, our multivariable analysis validates these results and does not show any significant seasonal variation in PTH rates in Australia.…”

“…A study by MacFarlane et al showed that monopolar diathermy was the most popular surgical technique used for tonsillectomies in Australia while studies in the United Kingdom found cold steel dissection as the preferred technique (3,14). Whilst studies in the past decade have identified a significantly higher rate of PTH in winter months (15)(16)(17), Cadd et al conducted the only Australian retrospective review of 941 tonsillectomies in Australia showing no significant seasonal variation in haemorrhage rates (18). However, local environmental factors such as temperature and season have been found to be associated with other conditions such as angina pectoris (19) and intracranial haemorrhage (20).…”

“…Currently, there are no multivariable analyses assessing potential risk factors associated with secondary PTH in an Australian setting, with previous studies investigating single factors such as post-operative analgesic use, patient age and surgical indications (3,18,21,22). Therefore, surgeons often rely on overseas data for comparison, which may not accurately reflect local practice.…”

Renal outcome after tonsillectomy plus corticosteroid pulse therapy in patients with immunoglobulin A nephropathy: results of a multicenter cohort study

“…Our study showed that they were the patients with CKD G1 and G2 whose proteinuria was ≧1.0g/gCre; it also showed that TSP may be better than-and at least equal to-SP for patients with CKD G3 and proteinuria ≧1.0 g/gCre, and distinctly better than OS and RAS. has been reported that the rate of post-tonsillectomy hemorrhage was 2.3~7.7% [34,35].…”
