Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Hypospadias, seen in every 200-300 births, is one of the most common congenital anomalies of the penis and is defined as the urethral meatus being located in the ventral part of the penis instead of its normal place. The surgery of this anomaly is very painful in the postoperative period and requires long-term analgesia. Regional anesthesia methods combined with general anesthesia play an important role in providing effective and long-term postoperative pain control in pediatric penile surgery. These methods also reduce postoperative morbidity, enable early mobilization and significantly decrease the need for narcotic analgesics.

The investigator's hypothesis is peripheral nerve blocks are superior to neuraxial blocks as the blocks provide longer-term analgesia and have fewer side effects.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The surgery of hypospadias is very painful in the postoperative period and requires long-term analgesia. A dorsal penile nerve block (DPNB) and caudal epidural block (CEB) are commonly used regional anesthesia techniques for postoperative pain control.

Aims: The primary aim of the current study was to use the duration until the first postoperative analgesic requirement after two different block techniques to compare the analgesic effect. The secondary aims were to compare the two methods for postoperative Children's Hospital Eastern Ontario Pain Scale (CHEOPS) scores, complications and parental satisfaction scores.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Dorsal penile nerve block group

Ultrasound (US) guided dorsal penile nerve block with in plane technique was done.

Half of the total 0.2 ml/kg dose of 0.25% bupivacaine was administered while observing its distribution with US. The same procedure was then repeated on the other side of the penis.

No interventions assigned to this group

Caudal epidural block group

A 22 G needle was inserted through the sacral hiatus. The loss of resistance method was used to pass through the sacrococcygeal membrane and enter the caudal epidural space. Negative aspiration was then performed 0.25% bupivacaine at a dose of 0.2 ml/kg was administered.

No interventions assigned to this group
