Background  Methamphetamine use is increasing in prevalence. There is a theoretical increased risk of complication postoperative due to catecholamine depletion. When presented with an urgent surgical problem, there are little data to help counsel the patient on the risks of undergoing surgery in the setting of a positive methamphetamine test result.  Aims and objectives  The aim of this study was to examine the perioperative complication rate for patients who underwent emergent orthopaedic procedures in the setting of a positive methamphetamine drug screen. Additional data were collected in an attempt to further stratify risk factors for perioperative complications in this patient population.  Design and methods  A retrospective case series of 110 patients. Patients were identified by querying the medical record for patients with a positive methamphetamine result within 24 hours of the surgery start time. Data were collected on each patient, including the nature of the surgery, the type of injury sustained, disposition from the operating room, among other data points. The primary outcome was the presence of a perioperative cardiopulmonary complication, as determined by a new diagnosis made in the chart. The secondary outcome was whether the patient needed an increased level of care postoperatively.  Results  Of the 110 charts reviewed, three patients sustained complications during their hospitalization; an overall complication rate of 2.7%. One patient developed acute respiratory distress syndrome (ARDS), while two others developed surgical site infections. Of the 19 patients who went to the intensive care unit (ICU) postoperatively, none were because the patient required a higher level of care than the preoperative level.  Conclusions  Patients who underwent emergent surgical intervention in the setting of a positive methamphetamine drug test had a low complication rate. While the dogma is to delay surgery in the setting of methamphetamine use, the true risk of undergoing surgery in this setting is not fully understood. We advocate for continued research in this poorly studied group of patients. Larger studies will need to be done in order to fully understand the risks associated with operating in the setting of a positive methamphetamine drug screen.
