The reticulocyte hemoglobin equivalent (RET-He) is presented as a biomarker for the diagnostics and monitoring of iron deficiency. The marker is independent of the acute phase and can be determined within a few minutes by a blood count. Due to the approximately 120-day lifetime of erythrocytes, iron deficiency and changes in the iron status of erythropoiesis can first be recognized at a relatively late stage using classical hematological parameters, such as hemoglobin, mean corpuscular volume, mean cellular hemoglobin content and also with determination of hypochromic erythrocytes (% hypo). ⋯ Changes in the iron status of erythropoiesis can thus be detected much earlier than by determining only the hemoglobin content of mature erythrocytes, i.e. the mean cellular hemoglobin content. It is recommended that the evaluation of RET-He should be carried out as an inexpensive routine preoperative marker of latent anemia in order to identify patients at risk. In the sense of a perioperative prehabilitation and the enhanced recovery after surgery (ERAS) concept, patients with iron deficiency can be treated proactively at an early stage in order to prevent complications and extended hospital stays.

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.
