Peng Block or Suprascapular Nerve Block for Postoperative Analgesia in Shoulder Artroscopy ?

Arthroscopic shoulder surgery, which has been frequently applied in recent years, provides long-term positive clinical results and increases the quality of life after surgery, while it can cause severe pain in the early postoperative period. Postoperative pain management is very important in shoulder arthroplasty. Adequate pain control; mental state, nutrition, cost of care, rehabilitation, and patient satisfaction, are of great importance for the patients' recovery and contribute to a successful surgical outcome.

In this study, the investigators aimed to compare the effects of suprascapular nerve block and shoulder pericapsular nerve block, which will be performed preoperatively with ultrasound, on the level of postoperative pain in patients who will undergo shoulder arthroscopy surgery under general anesthesia.

About this study

As a result of the power analysis the investigators conducted for this study, the minimum sample size was calculated as 32 people for each group, 64 people in total, at the 90% confidence interval.

64 patients who meet the inclusion criteria will be included in our study. The participants will be randomized and divided into 2 groups. Accordingly, the PENG block will be applied to 32 patients, and the suprascapular block will be applied to 32 patients.

Inclusion criteria

  • Patients who will have shoulder arthroscopy surgery under general anesthesia
  • Ages of 18-75
  • ASA I-III

Exclusion criteria

  • Patients with deformity and pathology in the shoulder region
  • Patients with known local anesthetic allergy
  • Patients with BMI>35
  • Patients with alcohol and substance addiction
  • Patients with opioid addiction
  • Patients who cannot perceive and evaluate pain, such as psychiatric illness, mental retardation

Treatment and study plan

Pericapsular Nerve Block

Procedure

The investigators will perform a pericapsular nerve block on that patient group for postoperative analgesia in shoulder arthroscopy.

Suprascapular nerve block

Procedure

The investigators will perform a suprascapular nerve block on that patient group for postoperative analgesia in shoulder arthroscopy.

Bupivacaine Hydrochloride

Drug

The investigators will perform a pericapsular nerve block on that patient group for postoperative analgesia with bupivacaine hydrochloride

Primary outcomes

  1. The primary outcome measure of the study is the patients' postoperative pain scores (NRS)

    Time frame: 36 hours postoperatively

    Numerical rating scale (NRS) at 1, 6, 12, 18, 24, 30, and 36th 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.

Secondary outcomes

  1. Postoperative 36-hour total tramadol hydrochloride consumption

    Time frame: 36 hours postoperatively

    This will be measured by the PCA device in the 36 hours after
