The efficacy of ultrasound-guided erector spinae plane block (ESPB) versus freehand ESPB in postoperative pain management after lumbar spinal fusion surgery: a randomized, non-inferiority trial

Erector spinae plane block as an anesthesia technique for an emergent thoracotomy; a case report

BACKGROUND

The erector spinae plane block (ESPB) is a novel regional block technique for pain management following thoracic surgeries. However, there are minimal cases in which the technique was used as the main anesthesia technique during surgery.

CASE PRESENTATION

Here, we report the successful use of ESBP for applying anesthesia in a case during an emergent thoracotomy for performing pericardiotomy and loculated tamponade evacuation.

CONCLUSIONS

Using ESPB with a higher concentration of local anesthetics, in this case, prepared appropriate anesthesia for performing an emergent thoracotomy while avoiding multiple needle insertions and the risk of further hemodynamic instability.

Comparison of Effectiveness and Safety of Oxycodone Hydrochloride and Fentanyl for Post-operative Pain Following Total Hip Arthroplasty: A Randomized Triple-Blind Trial

Background

Total hip replacement (THR) is frequently associated with intense post-surgical pain. Effective pain management is of crucial importance to improving patient's condition and increasing his/her satisfaction in the post-operative time.

Objectives

This study aimed to compare the analgesic effect and safety of oxycodone and fentanyl after THR.

Methods

Seventy-two cases scheduled for elective THR were included in this randomized, triple-blind trial. The patients were equally randomized into 2 groups: Fentanyl group (50 ug of fentanyl) and oxycodone group (oxycodone 4 mg). Drugs were received 20 min prior to the end of the operation.

Results

Post-operative visual analog scale (VAS) measurements at rest and movement at the post-anesthesia care unit (PACU) and in the ward, 2 h, 4 h, and 8 h post-operatively exhibited a significantly reduced value in the oxycodone group compared to the fentanyl group (P-value < 0.05). Time to first rescue for analgesia was delayed significantly in the oxycodone compared to the fentanyl group (P-value < 0.001). Fentanyl consumption (ug) in the 1st post-operative 12 h, 24 h, and 48 h decreased significantly in the oxycodone group compared to the fentanyl group (P-value < 0.001). Post-operative nausea, vomiting, headache, and pruritus were matched between the 2 groups (P > 0.05).

Conclusions

A bolus dose of 4 mg of oxycodone provided superior analgesic efficacy than 50 ug fentanyl as evidenced by significantly lower pain score, delayed onset to first request for analgesia, and the smaller amount of fentanyl consumption at 12, 24, and 48 h post-total hip arthroplasty compared to fentanyl. The incidence of adverse events was comparable between the 2 groups.
