start of 1:1-Block public summary

Brief Summary in Lay Language

In chest injuries, in rare cases even spontaneously, there may be an accumulation of air between the chest wall and the lungs. This accumulation of air can hinder breathing as well as lead to circulatory failure and is therefore a life-threatening situation. In an emergency situation, this accumulation of air is often punctured from the outside, through the chest wall, with a needle and the air is emptied. The puncture with a needle can lead to injuries of structures in the chest. Knowledge of the thickness of the chest wall and the width of the intercostal space is important for the emergency physician in order to minimize the risk of the injuries mentioned. For children, there are no reliable findings/data available so far. The thickness of the thoracic wall and the width of the intercostal space in children under 10 years of age will be measured by ultrasound in order to estimate the mentioned values in different age groups.

Brief Summary in Scientific Language

Decompression of a tension pneumothorax represents an immediately necessary and life-saving procedure in an emergency situation. For adults, there is sufficient data available on the thickness of the chest wall and the correlated probability of success of a needle puncture for decompression. These data are completely lacking for pediatric patients. The aim of the planned work is to measure the chest wall thickness and the width of the intercostal space using ultrasound at four locations (2nd ICR medioclavicular, 4th ICR anterior axillary line, on both sides). This will be done on children (0-10 years) who are planning to undergo surgery under general anaesthesia in pediatric surgery. The accuracy of the ultrasound examination will be validated on the basis of data collected by means of CT images. This should prove the reliability of the ultrasound measurements. In addition, an examination of the relationship between the expression of the variables collected and the age, height, weight and BMI of the children is carried out. The aim is to investigate which of these parameters correlates best with the thickness of the chest wall and the width of the intercostal space. The measurements are made after the anaesthetic has been administered and do not represent any additional burden or risk for the children. The additional time required for the measurements is approximately 2 minutes per child. In addition, the age of the children, height and weight are to be recorded. The data is collected anonymously.
