Clinical Trial Summary

Funnel chest deformation is a painful procedure, which requires high doses and long time used of opioids. It makes difficult introduction of ERAS protocol. Intraoperative cryolesia of intercostal nerves serves great relief of pain after this procedures. However ablation of the nerves needs 12-24 hours to achieve effects. During this time the high doses of opioids are needed. It causes side effects (sedation makes rehabilitation difficult). On the other hand, percutaneus cryoablation performed 12-24 hours before Nuss procedure needs repeated general anaesthesia. The investigators hypothesed that regional analgesia (erector spine plain block) performed just before intraopertive cryolesia may cover time to full cryolesia effect.


Description:

Severe pain in the post-Nuss procedure needs the use of many analgesic drugs, including opioids. It may cause adverse side effects and difficulties with rehabilitation. Moreover, it increases the risk of complications and prolonged hospitalisation. Cryoanalgesia as a part of multimodal analgesia offers better analgesia than single regional techiques with drugs and fasilitate introduction of the enhanced recovery after surgery (ERAS) protocol. However ablation of the nerves needs 12-24 hours to achieve effects. Regional analgesia (erector spine plain block) performed just before intraopertive cryolesia may cover time to full cryolesia effect. This Before - After Study is a single institution pilot study designed to compare intraoperative cryolesia alone (control group) with the intervention group (cryolesia and bilateral erector spine plane block). It is designed for better management of acute pain in the pediatric population diagnosed with funnel-chest and treated using the modyfied Nuss method. Control group received standard care with cryolesia using the Cryo-S Painless device (Metrum - Cryoflex Polska Limited) and multimodal analgesia according the current guidelines. The intervention group received all of the above and regional analgesia (erector spine plain block, ESP block). The aims of the study were the assessment the effectiveness of ESP block before full action of intraoperative cryoanalgesia as a method of acute pain control, safety of the method. The results were compared in terms of demographics, pain levels, side effects of the pain relief medications in the postoperative period and lenght of hospitalization.
