SmartPilot® view-guided anaesthesia improves postoperative outcomes in hip fracture surgery: a randomized blinded...

Area of Science:

• Anesthesiology
• Geriatric Surgery
• Medical Technology

Background:

• General anesthetic under- or over-dosage poses risks to frail patients.
• Optimizing anesthesia depth is crucial for patient safety during surgery.
• Hip fracture surgery presents unique challenges for anesthetic management.

Purpose of the Study:

• To evaluate the efficacy of computer-assisted anesthesia using SmartPilot® View (SPV) software.
• To optimize anesthesia depth and improve outcomes in hip fracture patients.
• To reduce the incidence of intraoperative hypotension and postoperative complications.

Main Methods:

• Prospective, randomized, single-center, blinded trial involving patients undergoing hip fracture surgery.
• Intervention group: anesthesia guided by SPV software with predefined targets.
• Control group: anesthesia managed by usual practice.
• Primary endpoint: time within the "appropriate anesthesia zone" (BIS 45-60, SAP 80-140 mmHg).

Main Results:

• Reduced consumption of propofol and desflurane in the SPV group.
• Significantly shorter duration of intraoperative hypotension (SAP <80 mmHg) in the SPV group (P=0.013).
• Fewer moderate/major postoperative complications (17% vs 36%, P=0.035) and shorter hospital stays (P=0.017) in the SPV group.

Conclusions:

• SmartPilot® View-guided anesthesia is effective in reducing intraoperative hypotension.
• This computer-assisted approach lowers the occurrence of postoperative complications.
• SPV-guided anesthesia leads to a reduced length of hospital stay for hip fracture patients.
