Among the 362 studies testing bupivacaine in Pain, Postoperative, from their registry updates:
This study evaluated whether bilateral erector spinae plane block (ESPB) performed before abdominal hysterectomy could reduce postoperative pain and the development of chronic and neuropathic pain. Adult patients undergoing abdominal hysterectomy under general anesthesia were assigned to receive either bilateral ESPB with bupivacaine or standard perioperative analgesic management without ESPB. Postoperative pain was assessed during the early postoperative period and at 1 and 6 months after surgery. Chronic and neuropathic pain were evaluated at 1 and 6 months using validated pain assessment tools.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
The anaesthetists’ scale of health before surgery: I is healthy, II has a mild illness that is under control, III a severe one, IV a severe illness that is a constant threat to life. V and VI are used for the critically ill and for organ donors.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Participants assigned to the ESPB group received bilateral ultrasound-guided erector spinae plane block at the T8-T9 level before surgery, with 20 mL of 0.25% bupivacaine administered on each side, in addition to standard perioperative analgesic management.
Drug: Bupivacaine
Participants assigned to the control group received standard perioperative analgesic management without erector spinae plane block.
Other: Standard Perioperative Analgesia
0.25% bupivacaine, 20 mL administered bilaterally as part of ultrasound-guided erector spinae plane block at T8-T9.
Participants received standard perioperative analgesic management according to the routine institutional protocol, without erector spinae plane block.
Chronic postoperative pain severity at 6 months
Chronic postoperative pain severity was assessed using the Numeric Rating Scale (NRS), ranging from 0 (no pain) to 10 (worst pain imaginable).
Time frame: 6 months after surgery
