Background: Retinopathy of prematurity is treated with laser photocoagulation under general anaesthesia with intubation using endotracheal tube (ETT), which carries a risk for postoperative mechanical ventilation (MV). Laryngeal mask airway (LMA) may provide a safe alternative. We assessed the need for postoperative MV in preterm infants who received LMA versus ETT., Methods: In this single-centre, retrospective cohort study, preterm infants who underwent laser photocoagulation between 2014-2021 were enroled. For airway management, patients received either LMA (n = 224) or ETT (n = 47). The outcome was the rate of postoperative MV., Results: Patients' age were 37 [35;39] weeks of postmenstrual age, median bodyweight of Group LMA was higher than Group ETT's (2110 [1800;2780] g versus 1350 [1230;1610] g, respectively, p < 0.0001). After laser photocoagulation, 8% of Group LMA and 74% of Group ETT left the operating theatre requiring MV. Multiple logistic regression revealed that the use of LMA and every 100 g increase in bodyweight significantly decreased the odds of mechanical ventilation (OR 0.21 [95% CI 0.07-0.60], and 0.73 [95% CI 0.63-0.84], respectively). Propensity score matching confirmed that LMA decreased the odds of postoperative MV (OR 0.30 [95% CI 0.11-0.70])., Conclusion: The use of LMA is associated with a reduced need for postoperative MV., Impact: Using laryngeal mask airway instead of endotracheal tube for airway management in preterm infants undergoing general anaesthesia for laser photocoagulation for treating retinopathy of prematurity could significantly decrease the postoperative need for mechanical ventilation. According to our current understanding, this has been the largest study investigating the effect of laryngeal mask airway during general anaesthesia in preterm infants. Our study suggests that the use of laryngeal mask airway is a viable alternative to intubation in the vulnerable population of preterm infants in need of laser treatment., (© 2024. The Author(s).)

Establishment of a proper hemodynamic monitoring system in order to achieve optimal care among critically ill patients is fundamental. In contrast to invasive patient-checking systems, which were introduced decades ago and used in both adult and pediatric intensive care, the non-invasive methods have become more popular in recent years due to technical advancements in intensive care and patient monitoring. This increase in popularity can be attributed to the higher degree of safety and reduced complication rates as well as to its being more economical. Our summary focuses on the ICON ® patient monitoring system. This newly engineered, non-invasive tool is based on electrical cardiometry, and uses hemodynamic parameters in both neonatal and pediatric care as well as in adults. The operating principle is simple: the conductivity of the blood in the aorta shows time-dependent changes. Prior to the opening of the aortic valve, the orientation of the red blood cells (RBCs) is random, and it is not until the contraction of the aorta that the RBCs and the opening of the aortic valve achieve a parallel position. The tool senses the conductivity between four placed electrodes, and measures the stroke volume (SV) and cardiac output (CO), before calculating other additional parameters (eg.: systemic vascular resistance) by tracing the variation of bioimpedance according to changes in the heart cycle. The most important advantages of ICON ® are the measurements that are made available immediately as well as continuously, and the low complication rate that originates from its non-invasive operation. ICON ® is a new, promising hemodynamic device in the tool belt of intensive care. Due to the nature of the device, it is possible to evaluate the status of the patient on a continuous basis, allowing for optimal care. To identify the more accurate clinical indications further measures will be necessary. Orv Hetil. 2018; 159(44): 1775-1781.

Introduction and Aim: We aimed to analyze patient characteristics of term neonates with hypoxic-ischemic encephalopathy treated with hypothermia at the 3rd level Neonatal Intensive Care Unit of the 1st Department of Pediatrics, Semmelweis University., Method: We conducted a retrospective cohort analysis between 2013-2015, including 97 asphyxiated neonates with HIE who received hypothermia treatment, using our in-house developed novel registry database., Results: 59.8% of neonates were born with Cesarean section and the first blood gas analysis showed a pH of 7.0 ± 0.2, pCO 2 55.9 ± 27.3 mmHg, base deficit 16.7 ± 7.2 mmol/l, and lactate levels of 13.3 ± 4.7 mmol/l (x ± SD). Hypothermia treatment was started during neonatal transport in 93.7% of the cases, at 2.5 ± 0.3 hours of age. Multiorgan failure associated with the perinatal asphyxia was present in 83.2% of the patients. Patients received intensive therapy for a median of 10.8 days, 61.3% of neonates were discharged home directly, 32.2% required further hospital treatment, and 6.5% died., Conclusion: Our novel registry database allowed for a quick, user-friendly and time-efficient analysis of patient characteristics in neonates with HIE. This registry could aid institutional audit work and prospective clinical data collection. Orv. Hetil., 2017, 158(9), 331-339.
