Randomized Controlled Trial
One-year outcome of the sevoflurane in acute myocardial infarction randomized trial.
Sevoflurane is an inhalation anesthetic that has cardioprotective effects. There is limited information regarding its use outside of the operating room and its potential protective effect for patients presenting with myocardial infarction. ⋯ In this study, we did not find an effect of sevoflurane on left ventricular function or myocardial injury at one year post STEMI. This trial was registered at www.clinicaltrials.gov ; identifier: NCT00971607.

Photoplethysmography permits continuous measurement of heart rate and peripheral oxygen saturation and has been widely used to inform clinical decisions. Recently, a myriad of noninvasive hemodynamic monitoring devices using this same technology have been increasingly available. This narrative review aims to summarize the principles that form the basis for the function of these devices as well as to comment on trials evaluating their accuracy and clinical application. ⋯ Although respiratory variations of the plethysmographic waveform correlate only modestly with the arterial blood pressure waveform, fluid responsiveness can be relatively consistently assessed using both approaches. Continuous blood pressure measurements obtained using the volume-clamp technique may be as accurate as conventional brachial noninvasive blood pressure measurements. Most importantly, clinical comparative effectiveness studies are still needed in order to determine if these technologies can be translated into improvement of relevant patient outcomes.

This manuscript proposes pharmacological strategies that might decrease persistent postsurgical pain (PPSP). These recommendations are based on a review of current publications available in the literature. ⋯ A winning strategy to reduce the incidence of PPSP may well involve performing minimally invasive surgery, providing adequate perioperative analgesia based on RA, and using a multimodal approach with NMDA antagonists.

We describe a case of a term parturient previously clinically diagnosed with hypermobility type Ehlers-Danlos syndrome (EDS) but later diagnosed with a genotype that may be associated with vascular type EDS. ⋯ The risk of severe morbidity and mortality in parturients with vascular EDS has warranted recommendations for modified management of labour, particularly regarding mode and timing of delivery. Nevertheless, a multidisciplinary approach and consideration of phenotype rather than genotype alone were instrumental in the successful management of this patient. Genetic testing of patients who display features of EDS and/or who have a positive family history of the disease is important in the preparation for labour and delivery. In the absence of convincing signs of vascular EDS and a negative family history, it may be rational to offer certain parturients neuraxial anesthesia and a trial of vaginal labour.
