BackgroundIn pursuit of improvement in cardiopulmonary resuscitation (CPR), new technologies for the measurement and assessment of CPR quality are implemented. In our study, we assessed the kinematics of the rescuer during continuous chest compression (CCC–CPR). The proper performance of the procedure is a survival predictor for patients with cardiac arrest (CA). The purpose of the study was a prospective assessment of the kinematics of the rescuer’s body with consideration given to the depth and rate of chest compression (CC) as the indicator of properly performed CC maneuver by professional and non-professional rescuers during a simulation of a 10-min CCC using a manikin.MethodsForty participants were enrolled in the study. CCC–CPR was performed in accordance with the 2015 AHA guidelines on a manikin positioned on the floor. Kinematic data on the movement were obtained from the measuring system (X-sens MVN Biomech) transmitting information from 17 inertial sensors. Measurement data were imported to the author’s program RKO-Kinemat written in the Matlab and C # environments. Two groups of results were distinguished: Group I—results of CC with the depth of ≥ 40 mm and Group 2—CC results with the depth of < 40 mm.ResultsThe multiple regression model demonstrated that the path length, left knee flexion angle, and left elbow flexion angle were the essential elements of the rescuer’s kinematics that facilitated achieving and maintaining the normal depth of CC.ConclusionsWe believe that raising the rescuer’s hips by moving the center of the rescuer’s body over the point of sternal compression increases the value of the CC force vector, thereby increasing the depth of CC. In addition, we observed that, during an effective CC, the rescuer was unable to maintain arms straight and, in consequence, a slight elbow flexion was observed. It, however, did not influence the quality of the maneuver.
Depth and rate of chest compression in CPR simulation during 10-minute continuous external cardiac compressionOcena głębokości i częstotliwości kompresji klatki piersiowej podczas symulacji resuscytacji krążeniowo-oddechowej, w trakcie 10-minutowego ciągłego zewnętrznego masażu serca AB ST R ACT I N T R O D U C T I O N:External cardiac massage has been a basic CPR maneuver for years. The aim of the study was to assess the quality of chest compression during a real-time continuous cardiac compression simulation on a cardiopulmonary resuscitation mannequin (considering medical rescuer experience and BMI). M A T E R I A L A N D M E T H O D S:This was a prospective study involving 17 medical rescuers, and 21 Medical Rescue students and university lecturers. During the simulation the participants performed continuous external cardiac compression for 15 minutes or until the refusal to continue. The depth and rate were analyzed at 60-second periods, leading to average values of cardiopulmonary resuscitation effectiveness. The analysis covered complete research data gathered in real time (10 minute periods). R E S U L T S:The average compression depth significantly decreased from the first (40.66 SE ± 0.80 mm) to the fourth minute of the study (38.21 SE ± 0.95 mm). The average compression rate was significantly different between the initial values (120.97 SE ± 2.83/min) and the sixth minute of the study (123.69 SE ± 2.55/min). The average compression depth amounted to n 36.03 SE ± 1.22 mm in non-professionals and 40.06 SE ± 1.37 mm in professionally active participants. In the participants with a BMI > 25, the only differentiating point in time was the beginning of the task when the average compression depth was 41.97 SE ± 1.12 mm. In the participants with a BMI < 25, there was a gradual decrease in the compression depth within the initial four minutes of the task.
During past 10 years 234 central venous access ports (CVAP) were implanted in 225 patients at the Department of Pediatric Hematology and Oncology in Zabrze. Mean exposure time was 745 days and total implantation time reached 173,768 days. Complications were encountered in 17 patients (7.6%). This mainly concerned central venous line infection, which led to removal of 10 CVAP (4.4%). The remaining complications necessitating removal of the CVAP consisted mainly of mechanical problems (catheter fracture, occlusion, and erroneous implantation to artery). In the opinion of the authors, subcutaneously implanted CVAP are a safe and effective option for high-dose chemotherapy deliverance in childhood cancer patients.
The aim of the study was to evaluate the influence of vitamin E administered intraperitoneally on the prevention of peritoneal adhesion formation in rats on the basis of macroscopic and microscopic assessment of the adhesions. material and methods. Experimental studies were performed on 50 Sprague-Dawley male rats, which were randomly divided into 5 groups, 10 rats in a group. Experimental group I (EI) included 10 rats which had peritoneal adhesions provoked by scraping of the wall of cecum and parietal peritoneum followed by intraperitoneal administration of vitamin E in the dose of 100 mg/kg body weight. Experimental group II (EII) included 10 rats which had peritoneal adhesions provoked by surgery, without administration of vitamin E. Control Group I (CI) included 10 rats which had the abdominal cavity opened without provoking peritoneal adhesions, and vitamin E was administered. Control Group II (CII) included 10 rats which had peritoneal adhesions provoked by surgery, and then lipid based solution was administered intraperitoneally. Control Group III (CIII) included 10 rats which had the abdominal cavity only opened and closed. Groups EI, CI and CII were the subject of the drugs intraperitoneal re-injection in first, second and third day after surgery. The animals were killed during the 8 th postoperative day. Macroscopic examination of peritoneal adhesions using the classification reported by Nair was performed and samples for microscopic examination were excised. Results. In group EI peritoneal adhesions were formed in 60% rats (40% weak and 20% solid). In group EII peritoneal adhesions were found in all animals (30% weak and 70% solid). Reduction of the inflammatory response and less severe fibrosis were observed in animals with intraperitoneal administration of vitamin E. conclusion. In the study, vitamin E administered intraperitoneally to rats decreased the intensity and extensiveness of peritoneal adhesions, which was confirmed by macroscopic and microscopic examinations.
