Does pulse lavage reduce hip hemiarthroplasty infection rates?

Area of Science:

• Orthopedic Surgery
• Infectious Disease Prevention
• Surgical Site Infection (SSI) Control

Background:

• Surgical site infections (SSIs) are a significant complication following hemiarthroplasty procedures.
• Effective wound irrigation techniques are crucial for minimizing infection risk.
• Current standard irrigation methods may not be optimal for deep wound environments.

Purpose of the Study:

• To compare the efficacy of pulse lavage versus standard saline washout in reducing SSIs after hemiarthroplasty.
• To evaluate the impact of irrigation method on deep joint space infections.
• To assess infection rates within 30 days post-surgery or discharge.

Main Methods:

• Prospective randomized trial across four hospitals in Southern England.
• Patients undergoing hemiarthroplasty (American Association of Anaesthetists grade IV and above) were randomized.
• Intervention groups received either 2-L pulse lavage normal saline washout or 2-L standard normal saline washout (jug/syringe).
• Wound surveillance and re-admission recording for infection up to 30 days post-discharge.

Main Results:

• The pulse lavage group demonstrated a significantly lower overall infection rate.
• A notable decrease in 'joint space' or deep infection rates was observed in the pulse lavage group.
• No significant difference in superficial infection rates was implied, focus was on deep infections.

Conclusions:

• Pulse lavage with normal saline is a superior method for reducing surgical site infections, particularly deep infections, following hemiarthroplasty.
• This technique offers a significant advantage over standard irrigation methods in preventing post-operative complications.
• Implementation of pulse lavage should be considered for routine practice in hemiarthroplasty to enhance patient safety.
