A Co-Induction Technique Utilizing 4% Sevoflurane Followed by 0.75 mg/kg Propofol in Elderly Patients Undergoing...

Area of Science:

• Anesthesiology
• Geriatric Medicine
• Urology

Background:

• Elderly patients represent a significant healthcare demographic.
• Aging leads to functional decline in multiple organ systems, complicating perioperative management.
• Safe anesthetic approaches are crucial for minimizing complications in older adults.

Purpose of the Study:

• To evaluate the safety and effectiveness of a standardized co-induction anesthesia technique.
• To minimize anesthesia-related complications in elderly patients undergoing urological procedures.

Main Methods:

• 105 patients (age ≥65, ASA II-III) undergoing endoscopic urological procedures were randomized into three groups.
• Groups received induction via propofol (1.5 mg/kg), sevoflurane (8%), or co-induction (4% sevoflurane followed by 0.75 mg/kg propofol).
• Laryngeal mask airway (LMA) insertion followed jaw relaxation.

Main Results:

• The co-induction technique demonstrated a favorable profile for respiratory adverse events.
• The sevoflurane group showed better hemodynamic stability.
• Transient apnea occurred in 68.6% of the sevoflurane group (p < 0.001), and partial laryngospasm in 17.1% (p = 0.034). The propofol group had lower blood pressures than the co-induction group (p < 0.05).

Conclusions:

• Co-induction with sevoflurane and propofol reduced respiratory adverse events compared to sevoflurane alone.
• This technique also led to less hemodynamic instability compared to propofol alone.
• The studied co-induction method offers a balanced approach to anesthesia in elderly patients.
