Filter by:The study is a prospective, randomised, controlled double-blind clinical trial. The primary aim was to evaluate the efficacy of caudal block and ilioinguinal-iliohypogastric nerve block with PI and PVI in pediatric inguinal hernia operations under general anesthesia. The secondary aim is to evaluate postoperative analgesic agent consumption and to evaluate the correlation of PI and PVI values with hemodynamic parameters. Pediatric patients between the ages of 2-8 years who are planned to undergo elective inguinal hernia operation will be included in the study. After the patients scheduled for inguinal hernia surgery are admitted to the operating room, routine monitoring will be performed as performed. In addition to routine monitoring, a Radical-97TM Pulse CO-OximeterTM (Masimo Corp, Irvine, CA, USA) probe will be attached to the toe to monitor PI and PVI. Patients will be given anaesthetic drugs as routinely administered. After LMA by randomisation by closed envelope method, caudal or ilioinguinal-iliohypogastric nerve block will be performed by an experienced anaesthetist as the investigators routinely perform in patients other than the control group.. PI, PVI, pulse, saturation, noninvasive arterial pressure values will be recorded before induction, after induction, after LMA, before applied block, after applied block (after surgical incision) at 0, 5, 10, 15, 20, 25 and 30 minutes and at the end of anaesthesia. All patients will be given paracetamol 10mg/kg iv, which is a routine intravenous (iv) analgesic, at the end of surgery. In case of perioperative complications, the complications will be recorded. Flacc pain scale (Face, Legs, Activity, Cry, Consolability) will be applied at 0, 2, 6 hours postoperatively. Postoperative analgesic use and discharge time will be recorded. Flacc pain scale will be performed by an anaesthetist blinded to the study.
Introduced in 1930, photoplethysmography techniques presented the possibility of measuring SpO2 and HR using the absorption of light by the blood to define these signals In recent years, a new approach to photoplethysmography to measure physiological parameters without contact has been developed. This technique, called remote Photoplethysmography Imaging (rPPG), uses the different Red - Green - Blue color spectra at a skin captured by the camera video to determine a plethysmography signal. Although these systems have been technically valid, they have not been clinically evaluated in a health setting. This clinical trial is to assess parameters measurements by rPPG compared standard acquisition system in real conditions
