By implementation of sonography for regional anesthesia, truncal blocks became more relevant in the daily practice of anesthesia and pain therapy. Due to visualized needle guidance ultrasound supports more safety and helps to avoid complications during needle placement. Additionally, complex punctures are possible that were associated with higher risk using landmarks alone. ⋯ The present review article describes published and clinically established puncture techniques with respect to the indications and procedures. The clinical value is reported according to the scientific evidence and the analgesic profile. Moreover, the authors explain potential risks, complications and dosing of local anesthetic agents.

At the beginning of the SARS-CoV‑2 outbreak, personal protective equipment (PPE) was scarce worldwide, leading to the treatment of patients partially without sufficient protection for the medical personnel. In order to be prepared for a new epidemic or pandemic or a "second wave" of COVID-19 outbreak and to meet a renewed deficiency of PPE, considerations were made on how personnel and patients can be better protected by appropriate provisioning. ⋯ The developed tool allows our hospital to estimate the necessary amount of PPE to be kept in stock for future pandemics. By taking local conditions into account this tool can also be helpful for other hospitals.

This is a case report of a 29-year-old female patient who developed unilateral mydriasis following the use of a scopolamine patch for the prevention of postoperative nausea and vomiting (PONV). Given a medical history showing multiple risk factors for PONV, a preauricular scopolamine patch was applied prior to the induction of anesthesia. General anesthesia was induced with 150 mg propofol and 25 μg sufentanil and maintained with total intravenous anesthesia, using propofol (5 mg/kg per h) and remifentanil (2-3 μg/kg per h). ⋯ It should be noted, however, that a dysfunctional accommodation is listed as a common side effect of the drug, affecting more than 1 in 10 patients. Even though the efficacy of scopolamine patches for the prevention of PONV is proven, clinicians should be aware of the common ophthalmological side effect. Particularly with respect to various surgical disciplines, where anisocoria may indicate an underlying surgery-related complication, the application of scopolamine patches should be well- considered.

Postdural puncture headache (PDPH) is a severe complication after spinal anesthesia. The aim of this study was to investigate the incidence of PDPH in two different operative cohorts and to identify risk factors for its occurrence as well as to analyze its influence on the duration of hospital stay. ⋯ The incidence of PDPH was different in the two groups with a higher incidence in the ORT but considerably lower than in the literature. Age, constitution and type of neuraxial anesthesia were identified as risk factors of PDPH. Considering the functional imitations (mobilization, neonatal care) and a longer hospital stay, future studies should investigate the impact of an early treatment of PDPH.
