Brief Summary

The pain experienced by participants after minimally invasive chest surgery (VATS) can make it difficult for them to take deep breaths, which can lead to problems with lung function. This can cause serious problems such as lung collapse, low oxygen levels, and infections, making recovery longer and more difficult. Managing pain well after surgery is important to prevent these problems and speed up recovery. In this study, we aimed to compare two pain relief methods, Erector Spinae Plane Block (ESP) and Paravertebral Block (PVB), in participants who underwent VATS. We will look at which method causes the smallest change in lung function before and after surgery.

Detailed Description

Video-assisted Thoracoscopic surgery (VATS) is a minimally invasive surgical method used in the diagnosis and treatment of diseases in the chest area. Thoracoscopic surgery has many advantages, such as being less invasive, less risk of complications, shorter hospital stay, and better cosmetic results. However, these participants may experience severe pain in the postoperative period, although not as much as in surgeries performed with open surgical methods, that is, thoracotomy. This pain, which occurs in the postoperative period in VATS methods, which is one of the minimally invasive methods, may prevent the participants from taking deep breaths, as well as cause deterioration of respiratory functions, serious pulmonary complications such as atelectasis, hypoxia and infection, and prolonged postoperative patient stay. As the development of morbidity and mortality. Delay or deterioration in postoperative respiratory functions is one of the most troublesome complications of thoracic surgery. It was reported that acute pain in the postoperative period should be effectively controlled with effective analgesia methods in order to prevent postoperative pulmonary complications and accelerate the patient's well-being. Controlling pain with postoperative analgesia allows participants to breathe more deeply, perform breathing exercises more effectively, and therefore improves and helps preserve respiratory functions. Although thoracic epidural analgesia is the gold standard method in thoracic surgery, intravenous analgesic techniques and thoracic trunk nerve blocks are increasingly recommended for postoperative analgesia in less invasive VATS operations. Thoracic trunk blocks have effects on hemodynamics, respiratory functions, and consciousness; It has important advantages such as having fewer side effects than systemic analgesic techniques and being less invasive than thoracic epidural analgesia. Body blocks are recommended as a first-line analgesia program, especially in thoracic surgery, as they shorten postoperative recovery time, reduce the risk of pneumonia and provide early postoperative mobilization. The ease of application of the erector spinae plane block (ESP), its low risk of complications, and its ability to provide effective analgesia, especially in minimally invasive surgeries, have increased its use. Paravertebral block (PVB), one of the other blocks, is frequently used because it is more reliable and provides effective analgesia compared to thoracic epidural analgesia and conventional analgesia methods. Thoracic trunk plane blocks can significantly reduce intravenous opioid use and prevent side effects related to opioid use with the effective analgesia they provide in the early postoperative period, increase participants' comfort and painlessness, and accelerate recovery while preventing deterioration in respiratory function parameters. during rest and mobilization. Because; It is thought that by applying erector spinae plane block (ESP) or paravertebral block (PVB), postoperative pain scores and opioid consumption will decrease significantly and respiratory functions will return earlier. In this study, we aimed to evaluate the effects of ESP or PVB on respiratory functions in the early postoperative period in patients undergoing VATS, and in which block there would be less percentage change between preoperative and postoperative respiratory function test (PFT) parameters.

Pain is a symptom known to be subjective and will be queried with a standardized scale, the visual pain score scale (VAS), to minimize differences between participants. Postoperative rest and movement pain scores (VAS; 0, 1, 2, 4, 6, 12, 24 and pre-discharge scores), postoperative 6th hour, 24th hour and predischarge pulmonary function test (PFT) parameters, total Analgesic consumption will be recorded at 0, 1, 2, 4, 6, 12, 24 hours and before discharge.

Forced Vital Capacity (FVC), Forced Expiratory Volume in 1 Second (FEV1), FEV1/FVC, Peak Expiratory Flow (PEF) values will be recorded as Respiratory Function Test parameters.

The total narcotic analgesic needs of the participants who received the block will be recorded with the PCA device placed intravenously postoperatively and their total Morphine consumption will be recorded.

Participants' satisfaction after the procedure will be questioned with a Likert score before discharge.

Side effects such as nausea and vomiting that may occur in participants will be questioned with the simplified post-operative nausea and vomiting impact scale.

Participants' demographic characteristics, comorbidities, operation times and complications will be recorded and statistically analyzed.

Study Groups

ESP Group

Patients in this group will receive the Erector Spinae Plane Block (ESP) as a method of postoperative pain management.

Erector Spinae Plane Block (ESP)

Intervention Type: PROCEDURE

The ESP block will be administered before the VATS procedure, aiming to manage postoperative pain and minimize the impact on early lung function test (SFT) parameters. The block will be performed using standard techniques under ultrasound guidance to ensure accurate placement.

Paravertebral Group

Patients in this group will receive the Paravertebral Block (PVB) for postoperative pain relief.

Paravertebral Block (PVB)

Intervention Type: PROCEDURE

The PVB will be administered prior to the VATS procedure, with the objective of managing postoperative pain and assessing its impact on early postoperative lung function (SFT) parameters. This block will also be performed using standard techniques and ultrasound guidance for precision.
