Brief Summary

This study evaluates the analgesic effects of ultrasound-guided regional techniques, Thoracic Paravertebral Block (TPVB), Erector Spinae Plane Block (ESPB) and Serratus Anterior Plane Block(SAPB) by comparing postoperative total morphine consumption, first analgesic requirement time, and postoperative pain scores ( FLACC/NRS), postoperative chronic pain in 3rd month in pediatric patients undergoing thoracic surgery. The investigators also aim to observe the side effects of these techniques such as nausea, vomiting, bradycardia, hypotension, respiratory depression

Detailed Description

Thoracic surgery is one of the most common causes of postoperative severe pain due to the damage to intercostal nerves, irritation of the pleura and rib retraction. Effective analgesia provides patient comfort and enables early mobilization, reducing complications such as pneumonia, respiratory failure, hypoxia, and hypercapnia. In pediatric patients, nonsteroid anti-inflammatory drugs, opioids and regional analgesia techniques can be used for multimodal analgesia. Several side effects of opiates such as respiratory depression, nausea, vomiting, itching, addiction, and sedation effect patients' comfort and delay discharge. Nowadays US-guided truncal block techniques such as thoracic paravertebral block (TPVB) become popular. TPVB provide the somatosensorial and visceral block with an injection of the local anaesthetic agent into the paravertebral space. Existing evidence demonstrates the non inferiority of TPVB compared with TEA for postoperative analgesia and TPVB can reduce side effects. Erector Spina Plan Block (ESPB) was first described in 2016 as an ultrasound-guided truncal block for thoracic neuropathic pain and now ESPB uses for many different thoracics and abdominal surgeries for postoperative analgesia. Several studies have shown that ESPB can provide adequate analgesia in postoperative thoracic pain. ESPB is gaining popularity because its application is easy and safe compared with TPVB. Another new US-guided regional anaesthetic block technique, the serratus anterior plane block (SAPB), targets the plane above or below the serratus anterior muscle in the midaxillary line and provides analgesia to a hemithorax by blocking the lateral branches of the intercostal nerves, thoracicus longus and thoracodorsal nerves. The SAP block provides analgesia to the 2nd and 9th thoracic dermatomes. The SAP block is safe, and easy to perform, owing to its easy-to-learn technique and distinct bony landmarks. So, it can be an attractive alternative for pain relief after thoracic surgery.

In this study, Investigators aim to compare the efficacy of these three techniques in pediatric patients. The primary hypothesis is the analgesic efficacy of SAPB will be equivalent to TPVB and RSPB. The primer outcome is postoperative total narcotic analgesic consumption in 24 hours. The seconder outcomes are; time of postoperative first analgesic requirement, postoperative pain scores (FLACC - NRS) in 0.-15.-30.-45.minutes and 1.-2.-6.-12.-24.-48. hours, chronic thoracic pain 3 months after surgery, intraoperative additional fentanyl requirement, postoperative additional paracetamol requirement, intraoperative hemodynamic parameters, first mobilization time, side effects, technical complications, and the satisfaction of patient-surgeon.

Primary Outcome Measures
NameTimeMethod
Postoperative Iv Morphine ConsumptionUp to 24 hours

The total dosage of iv morphine consumption in 24 hours.

Secondary Outcome Measures
NameTimeMethod
Time of Postoperative First Analgesic Requirement TimeUp to 48 hours

Time of postoperative first analgesic requirement time.

Face, Legs Avtivity, Cry, Consolability (FLACC) scoresUp to 48 hours

It corporates five categories of behavior, each scored on 0-2 point scale so that total score ranges from 0 to 10. Total scores of 0-3 is defined as mild or no pain, 4-7 as moderate, and 8-10 as severe pain

Postoperative NRS Score (Numeric Rating Scale)Up to 48 hours

A numerical rating scale (NRS) requires the patient to rate their pain on a defined scale. For example, 0-10 where 0 is no pain and 10 is the worst pain imaginable

Additional IV Paracetamol Dosage In The Postoperative PeriodUp to 48 hours

15mg/kg iv paracetamol will be administered 30 minutes before extubation. In the postoperative follow-up that will be performed every 6 hours,15mg/kg iv paracetamol will be administered if the FLACC score is \>3 or the NRS score is \>4.

Intraoperative Heart Rate (beat/min)Intraoperative Period

To be measured through the operation at intervals of 5 minutes

Intraoperative Mean Arterial Pressure(MAP)(mmHg)Up to end of the operation

To be measured through the operation at intervals of 5 minutes

Chronic Thoracic PainUp to 3 months

Presence of thoracic pain due to the incision after 3 months of the thoracic surgery.

Number of patients who need intraoperative additional FentanylUp to end of the operation

Intraoperative Additional Fentanyl Requirement

Length of Hospital StayUp to first week
