Procedure: spinal anesthesia
Procedure: general anesthesia
Registration Number
NCT06425627
Lead Sponsor
Tongji Hospital
Brief Summary

The objective of this study was to investigate the difference in postoperative pulmonary complications (PPCs) between spinal anesthesia and general anesthesia in patients undergoing delayed hip surgery.

Detailed Description

In this study, the difference of 30 min arterial partial pressure of oxygen after operation was used as the main outcome index. By means of pulmonary ultrasound, pulmonary function monitoring and other physical and biochemical examinations, the difference of postoperative pulmonary complications between spinal anesthesia and general anesthesia in patients with delayed operation of hip fracture longer than 48 hours was compared.

GroupInterventionDescription
spinal anesthesiaspinal anesthesiaPatients underwent real-time ultrasound guided spinal anesthesia. The maximum attempts of skin piercings are 3, and the total redirections of each skin piercings should not exceed 6 times. General anesthesia was considered if three skin piercings were unsuccessful.
general anesthesiageneral anesthesiaRapid sequential induction was performed with sufentanil 0.5 ug /kg, etomidate 0.3 mg /kg, cisatracurium 0.15 mg /kg, and then laryngeal mask was applyed. Parameter settings: tidal volume: 6-10 mL/kg, 1.5 \~ 2.0% sevoflurane inhalation, remifentanil 0.1 \~ 0.2 ug/ kg.min-1. Mechanical driving pressure was applyed by PEEP titration method.
Primary Outcome Measures
NameTimeMethod
Arterial partial pressure of oxygen, PaO230 minutes after surgery

PaO2 was measured by arterial blood gas analysis

Secondary Outcome Measures
NameTimeMethod
Forced vital capacity, FVC30 minutes before surgery; 30 minutes after surgery; 24 hours after surgery

FVC was measured by Spirometer (SP70B)

Peak expiratory flow, PEF30 minutes before surgery; 30 minutes after surgery; 24 hours after surgery

PEF was measured by Spirometer (SP70B)

Lung Ultrasound Score (LUS)30 minutes before surgery, 30 minutes after surgery, 24 hours after surgery

Bedside measurements using portable ultrasound

Postoperative pulmonary complicationsup to one month

Pulmonary complications (PPCs) include: (1) Evidence of pneumonia, pneumothorax, atelectasis and pleural effusion indicated by postoperative pulmonary ultrasound, chest film or chest CT; ② After surgery, the patient developed bronchospasm, ARDS, O2 requirement (nasal catheter or mask), non-invasive ventilation requirement, or unplanned endotracheal intubation/mechanical ventilation for more than 1 day; ③ The increase of inflammatory biochemical indexes 24 h after surgery suggested systemic inflammatory response (blood routine, C-reactive protein CRP, procalcitonin PCT and IL-6, IL-1β, TNF-α).

Arterial partial pressure of oxygen, PaO230 minutes before surgery

PaO2 was measured by arterial blood gas analysis

Forced expiratory volume in 1 second, FEV130 minutes before surgery; 30 minutes after surgery; 24 hours after surgery

FEV1 was measured by Spirometer (SP70B)

PEF 25, 75, and 25-7530 minutes before surgery; 30 minutes after surgery; 24 hours after surgery

PEF 25, 75, and 25-75 were measured by Spirometer (SP70B)

Hip mobility (Harris hip score, HHS)up to one month

The Harris scale was used to score. Range:0-100. A total Harris hip score below 70 points was considered a poor result, 70 to 80 fair, 80 to 90 good, and 90 to 100 excellent.
