Spinal anesthesia (SA) in pediatrics began to be used in the late nineteenth century in multiple procedures, with priority for high-risk and former preterm infants, for its suggested protective role compared to the development of postoperative apnea with general anesthesia (GA). In children, higher doses of local anesthetics are required with a shorter duration of action and a greater hemodynamic stability compared to adults. The puncture must be performed in the L4-L5 or L5-S1 spaces to prevent spinal injuries. ⋯ The drugs most commonly used for SA are tetracaine and bupivacaine alone or with adjuvants. SA complications are rare and often without consequences, except for postdural puncture headaches and backaches. Although SA is today considered safe and effective for pediatric patients, it remains relatively underutilized compared to GA.

Airway pressure curve: a good tool to measure neural inspiratory time?
Considerable asynchrony during pressure-support ventilation has been reported. While the beginning of active inspiration is usually identifiable in the airway pressure (Paw) curve (the inspiratory trigger), there is still a need for accurate, non-invasive methods to identify the end of inspiration. To test the hypothesis that inspiration, particularly the end of inspiration, can be estimated from the Paw curve, we compared indirect measurements based on Paw with simultaneous direct electromyography of the diaphragm (EMGdi). ⋯ The end of neural inspiration (EMGdi) can be easily and with little error recognized from the Paw curve alone in patients with normal ventilatory mechanics who receive pressure-support ventilation.

Case ReportsUsefulness and limits of near infrared spectroscopy monitoring during endovascular neuroradiologic procedures.
Transcranial cerebral oximetry (TCCO) with near-infrared spectroscopy (NIRS) is a non-invasive, bedside technique, which allows the continuous measurement of regional cerebral oxygenation. The aim of this study was to evaluate TCCO monitoring during endovascular neuroradiologic procedures. ⋯ TCCO with NIRS is a promising monitoring tool to assess the balance between oxygen supply and demand during neuroradiologic procedures. Nevertheless, some limits should be acknowledged, such as the study of the posterior circulation and artefacts related to contrast agent injection. A careful understanding of the undergoing step of the procedure as well of the possible influence of intrinsic and extrinsic factors affecting recording is important for interpretation of data.

Case ReportsManaging patients whose family members are physicians.
The ethical complexities involving physicians who treat their own family members are well known and it is generally accepted that such practice should not occur. We present three anonymous cases in which patient family members who worked as physicians complicated the medical care of their hospitalized relatives. ⋯ Clinician-relatives need to allow the medical team to assume the role of caretaker when their family members are hospitalized. Teams may need to employ limit setting in order to ensure fair and consistent care for all patients on the ward, and to prevent escalation of emotionally charged situations.
