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.
Interventions
An intrathecal anesthetic technique.
An intravenous (combined with inhalation) anesthetic technique.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Arterial partial pressure of oxygen, PaO2 | 30 minutes after surgery | PaO2 was measured by arterial blood gas analysis |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Arterial partial pressure of oxygen, PaO2 | 30 minutes before surgery | PaO2 was measured by arterial blood gas analysis |
| Forced vital capacity, FVC | 30 minutes before surgery; 30 minutes after surgery; 24 hours after surgery | FVC was measured by Spirometer (SP70B) |
| Forced expiratory volume in 1 second, FEV1 | 30 minutes before surgery; 30 minutes after surgery; 24 hours after surgery | FEV1 was measured by Spirometer (SP70B) |
| Peak expiratory flow, PEF | 30 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 complications | up 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). |
| 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. |
| PEF 25, 75, and 25-75 | 30 minutes before surgery; 30 minutes after surgery; 24 hours after surgery | PEF 25, 75, and 25-75 were measured by Spirometer (SP70B) |
Other
| Measure | Time frame | Description |
|---|---|---|
| Adverse outcomes | up to one month | Documented side effects associated with the intervention by an unwitting third party |
