Brief summary

The purpose of this study is to asses whether the pressure used for the pneumoperitoneum during laparoscopic surgery in children affects their postoperative pain levels.

Inclusion criteria

* Prepped and consented for diagnostic laparoscopy for likely acute appendicitis * 5 years or older * 15 kg or more * Parents/legal custodian give consent, patient shows no signs of unwillingness to participate * Patient is hemodynamically stable

Exclusion criteria

* Clinical signs of four quadrant peritonitis as a clinical sign of perforated appendicitis * Suspected perityphlitic abscess on preoperative ultrasound * Preexisting conditions making postoperative assessment of extent of pain and its localization very difficult or impossible, e.g. conditions that are associated with pronounced developmental delays or with communication difficulties * Parents have inadequate knowledge of German language to understand Informed consent * Child has inadequate knowledge of German language to allow elicitation of Pain Scores

Design outcomes

Primary

MeasureTime frameDescription
Postoperative pain score on postoperative day one (abdominal pain)Postoperative day one.Postoperative pain score for abdominal pain on postoperative day one after laparoscopic appendectomy using the Faces Pain Score Revised (FPS-R score), a self-reported pain score using drawn faces with values from 0 (no pain) to 10 (most pain). It is validated for use in studies with children.

Secondary

MeasureTime frameDescription
Postoperative pain scores during postoperative phase (abdominal pain)Through study completion, an average of 3 daysPostoperative pain score for abdominal pain on further postoperative days (excluding day one, which is primary outcome) after laparoscopic appendectomy using the Faces Pain Score Revised (FPS-R score), a self-reported pain score using drawn faces with values from 0 (no pain) to 10 (most pain). It is validated for use in studies with children.
Postoperative pain scores during postoperative phase (shoulder pain)Through study completion, an average of 3 daysPostoperative pain score for shoulder pain during hospitalisation after laparoscopic appendectomy using the Faces Pain Score Revised (FPS-R score), a self-reported pain score using drawn faces with values from 0 (no pain) to 10 (most pain). It is validated for use in studies with children.
Length of operationIntraoperativeLength of operation in minutes
Length of stayThrough study completion, an average of 3 daysLength of stay in hospital in hours
