As the availability of various bioelectric impedance analysis (BIA) tools is increasing, the patient’s position during the test may be of significant importance for the comparability of the results. An observational pilot study was undertaken between March and May 2021 at the Center for Innovative Research in Medical and Natural Sciences at the University of Rzeszow, Rzeszów, Poland. All participants (n = 49: M: 21.05 y ± 1.12 vs. F: 21.34 y ± 2.06) were subjected to measurements of selected nutritional status indicators and body components in three positions: lying, sitting and standing. The body composition indicators were obtained using a bioelectrical impedance device, AKERN BIA 101 Anniversary Sport Edition Analyzer (Akern SRL, Pontassieve, Florence, Italy). The results were analyzed using dedicated software (BodygramPlus 1.2.2.12 from AKERN 2016, Florence, Italy). Our observations indicate that there is a significant difference between lying and standing as well as sitting and standing with respect to anthropometric and nutritional indicators (resistance, reactance, phase angle, standardized phase angle, body cell mass index and fat-free mass index) and body composition components, with particular reference to intracellular and extracellular water. The described differences are significant for both sexes. This study showed that this significantly influenced the scores of components directly related to resistance, reactance and hydrated cell mass, while not affecting the percentages or absolute values of fat and fat-free mass.

Currently, pain is considered the fifth vital sign, and its effective relief is a priority in many surgical departments. The aim of this study was to determine the influence of selected factors on the intensity of postoperative pain after orthopedic and gynecological procedures. The study was conducted in a group of 200 patients undergoing orthopedic and gynecological procedures at the County Hospital in Nisko between August 2017 and January 2018. The method of estimation and document analysis was applied in the course of the study. A standardized tool was used—Polish adaptation of the Melzack Pain Questionnaire (MPQ), an individual documentation of patients and a scientific and research questionnaire developed by the authors. The tests were conducted for three consecutive days from the day of the operation. The strongest pain immediately after surgery was experienced by the patients after general endotracheal anesthesia, and the mildest after full intravenous short-term anesthesia (p < 0.05). Procedures lasting more than 60 min were associated with greater pain intensity on all tested days. The sex of the patient did not significantly affect the level of the perceived intensity of postoperative pain (p > 0.05). The highest intensity of pain occurred on day 0 after surgery, with a declining trend in the following days (p < 0.001). The highest intensity of postoperative pain was caused by gynecological procedures as well as laparotomy and arthroplasty (p < 0.001). The variability of the results indicates the need for an individual approach to each patient, both in pain assessment and treatment. Therefore, continuous improvement of the quality of health services provided in accordance with the guidelines for pain relief is necessary.
