Infectious Adverse Events Following Acupuncture: Clinical Progress and Microbiological Etiology

Abstract

BackgroundWe investigated the clinical progress and bacteriological characteristics of infectious adverse events (AEs) following acupuncture and compared patient characteristics between serious and non-serious outcome groups.MethodsA retrospective observational study was conducted in 1,174 patients with infectious complications associated with acupuncture at the emergency department (ED) in a tertiary hospital in Korea between 2010 and 2014. Serious outcome was defined as development of septic shock, admission to intensive care unit (ICU) or attaining permanent morbidity.ResultsForty-eight patients had certain causality and cellulitis, necrotizing fasciitis and osteomyelitis were common in order. Among them, 9 patients (18.8%) were categorized into serious outcome group, and they showed devastating outcomes such as septic shock (n = 2), ICU admission (n = 4), and permanent sequelae (n = 5). The serious group had delayed admission to the ED after acupuncture (30.0 [4.0–55.0] vs. 3.0 [1.0–10.0] days, P = 0.023). Methicillin-sensitive Staphylococcus aureus was the most frequently identified microorganism. The patients in the serious group required longer treatment duration (139.0 [49.0–183.5] vs. 14.0 [7.0–34.0] days, P < 0.001) as well as more operation with local (44.4% vs. 10.3%, P = 0.031) or general anaesthesia (33.3% vs. 2.6%, P = 0.017).ConclusionThe infectious AEs after acupuncture may cause serious outcomes. Patients and primary physicians should be aware of the risk of infectious complications and make efforts to prevent them.

Effect of low frequency repetitive magnetic stimulation at Shenmen (HT7) on sleep quality in patients with chronic insomnia

“…[ 29 ] Patients in China are usually familiar with acupuncture, and expect to receive acupuncture treatments. Thus, since acupuncture is often regarded as an invasive operation, [ 30 ] it is difficult to replicate its manipulations in clinic and design a nonpenetrating sham acupuncture in trial. [ 31 ] Hence, aim to improve subjects compliance and achieve acupoint effect, we choose rMS at HT7 acupoint in the experimental group in a high-quality randomized controlled trial.…”

Auricular acupressure for overweight and obese individuals

“…In a study conducted by Kim et al, [7] subjects were taught to adhere seeds on acupoints based on ballpoint pen markings and photos of acupoints on their auricles. However, the procedure of stimulating acupoints by needle with or without electricity may cause adverse events [16,17] and should be done by Chinese medical doctors or acupuncturists.…”

Efficacy and mechanism of acupuncture for ischemic poststroke depression

“…[35] Patients in China are usually familiar with acupuncture, and expect to receive acupuncture treatments when they participate in this kind trial. Apart from this, because acupuncture is often regarded as an invasive operation, [36] it is difficult to design a nonpenetrating sham acupuncture, which does not produce any physiological effects, [37] and would not be experienced and recognized by patients at home. However, to improve subject compliance and achieve blinding, sham acupuncture will be necessary in the control group, whereas placebo pills will be adopted in experimental group in a high-quality RCT.…”
