Study summary

The most important problem in the postoperative period in patients scheduled for pectus deformity correction surgery is pain. Due to the catastrophic neurological complications of thoracic epidural analgesia, the tendency towards plane blocks has been increasing in recent years. Serratus Plane Block (SAP Block), performed under ultrasound guidance, is used to treat pain in thoracic surgery. However, whether it has an effect on sternum pain is still controversial and there are not enough studies. Transversus thoracic plane block (TTP Block) provides effective analgesia in sternotomies. For this reason, we aimed to show that the TTP block added to the SAP block will provide more effective analgesia in order to provide adequate analgesia for the pressure and pain sensation of the bars placed on the sternum in pectus surgery.

Read the detailed description

The most important problem in the postoperative period in patients scheduled for pectus deformity correction surgery is pain. It is very important for patients to start active breathing exercises and mobilize early. Complications develop less frequently in patients who actively breathe and mobilize early. The tolerability of the surgery by the patient and the absence of pain in the postoperative period ensure early discharge .

What researchers measure

Primary outcomes

  1. Effect of Serratus Anterior Plane Block and Transthoracic Plane Block Combination on Postoperative Analgesia in Pectus Surgery

    Serratus Plane Block (SAP Block), performed under ultrasound guidance, is used to treat pain in thoracic surgery. However, whether it has an effect on sternum pain is still controversial and there are not enough studies. Transversus thoracic plane block (TTP Block) provides effective analgesia in sternotomies. For this reason, TTP block will be added to the SAP block in order to provide adequate analgesia for the pressure and pain sensation of the bars placed on the sternum in pectus surgery. The patient's pain score will be evaluated with the Numerical Rating Scale (NRS). Hourly pain scores in the postoperative period are 0./1./4./6./12./18./24./48. Additional complications

    Time frame: postoperative 48 hours

  2. Postoperative Analgesia in Pectus Surgery

    Total amount of analgesia for 48 hours,

    Time frame: postoperative 48 hours

  3. Postoperative pain in Pectus Surgery

    Presence of need for additional analgesics,

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
