.
No active participation only data collection from medical journal systems.

Data is to be collected concerning the patients gender, postnatal age, weight, amount opioids given during and after surgery, Time in Pediatric Intensive Care Unit (PICU) as well as in hospital. Time on ventilator and wound healing,Type of regional anesthesia eg. paravertebral block. Information of what kind of analgesic drugs that has been used
.
The overall duration of observation time is from admission to the surgical unit before surgery until discharge from hospital.

Summary
Brief summary
The hypothesis is that the patients who received a paravertebral block during surgery is in less need for additional opioids both peri and postoperatively.
We are also investigating if there are differences between length of stay on the ventilator, at the Pediatric Intensive unit as well as at the hospital between those who received a paravertebral block as opposed to those who did not.
