About this study
Official title: Efficacy of Combined Nalbuphine-bupivacaine Versus Dexamethasone-bupivacaine in Pericapsular Nerve Group Block (PENG) for Postoperative Analgesia in Hip Surgeries: A Randomized Clinical Study
The aim of the study to Evaluate the efficacy of nalbuphine-bupivacaine vs dexamethasone-bupivacaine in ultrasound guided pericapsular nerve group (PENG) block for improving pain management, reducing opioid consumption, and enhancing the overall analgesic effect in patients undergoing hip surgeries.
Read the detailed description
- To measure the time of first request of rescue analgesia , the total amount of rescue analgesic consumption (pethidine) in the first 24 hours post-operatively in each group and number of patients received one or two doses rescue analgesia.
- To assess pain score by using numerical rate scale (NRS) at rest (static) and during passive flexion or extension of hip (dynamic).
- To assess the incidence of drug-related side effects (such as nausea, vomiting, bradycardia, hypotension, sedation and hyperglycemia) or block -related side effects (hematoma, infection or LA toxicity) in patients receiving either nalbuphine or dexamethasone as adjuvant to bupivacaine in the PENG block.
- To assess Ease of Spinal Positioning (EOSP).
- To assess patient satisfaction.

Group DexamethasoneProcedure or surgery
Patients will receive a unilateral ultrasound-guided PENG block with a combination of 20 mL of bupivacaine 0.25%- 1 ml dexamethasone (4 mg) and 1 ml saline, with total volume 22ml
| Study group | Role | What they receive |
|---|---|---|
| Group Bupivacaine + nalbuphine (N) | Active comparator | Patients in this group will receive a unilateral ultrasound-guided pericapsular nerve group (PENG) block with a combination of 20 mL of bupivacaine 0.25%- and 2 ml nalbuphine (20 mg), with total volume 22ml Receives: Procedure: Group Nalupnine |

What is being measured
The primary outcome is the main question the study is designed to answer.
The time to first request of rescue analgesia
(time from end of local anesthetics injection in PENG block till time of NRS >3) will be recorded.
Measured: 24 hours postoperative
Secondary outcomes (7)
postoperative pain by Numerical Rating Scale
To assess pain score by using numerical rate scale (NRS) at rest (static) and during passive flexion or extension of hip (dynamic) at different time points
Measured: Basal (before giving the block), 15 minutes after giving the block and before spinal anesthesia, PACU ( after arrival to PACU 0 minute), 2 hours (hrs), 4 hrs, 8 hrs, 12 hrs and 24 hrs.
To assess the total amount of rescue analgesic consumption
To assess the total amount of rescue analgesic consumption in the first 24 hours post-operatively in each group
Measured: 24 hours postoperative
To assess the incidence of drug-related side effects or block -related side effects
To assess the incidence of drug-related side effects (such as nausea, vomiting, respiratory depression and hyperglycemia) or block -related side effects (hematoma, infection or LA toxicity) in patients receiving either nalbuphine or dexamethasone as adjuvant to bupivacaine in the PENG block.
Measured: 24 hours postoperative
Ease of Spinal Positioning (EOSP)
evaluated on a scale from zero to three (zero = unable to be positioned; one = abnormal posture of the patient due to pain requiring support for positioning; two = mild discomfort but no need for assisted positioning; three = optimal condition where the patient could sit without feeling pain)
Measured: up to 15 minutes after giving the block
patient's satisfaction
overall degree of satisfaction of the analgesia by using a 5-points Likert-like verbal scale (1 = very dissatisfied analgesia, 2 = dissatisfied analgesia, and 3 = neutral, 4=satisfied analgesia, and 5=very satisfied analgesia)
Measured: 24 hours postoperative
Number of patients received one or two doses rescue analgesia
Number of patients received one or two doses rescue analgesia (pethidine) postoperative
Measured: 24 hours
Length of hospital stay
number of hospital stay days starting from PACU discharge till home discharge
Measured: up to 5 days

The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Jan 2026; AzTrials last refreshed its copy on 8 Nov 2026.
