Objective:To build enhanced recovery after surgery (ERAS) ward management system based on the staff, stuff, structure space and systems (4S) management model, and explore the implementation effects of accelerated rehabilitation nursing management.Methods:A retrospective analysis was carried out on the implementation process of ERAS before 2020 in the Department of Hepatobiliary and Pancreatic Surgery, Ningbo First Hospital, Zhejiang Province. It was found that there were problems such as imperfect multidisciplinary team personnel, lack of systems, and lack of standardized process implementation rules. In April 2020, we created an ERAS ward based on the concept of 4S management model, improved the multi-disciplinary professional staff, equipment and venues, and formulated an ERAS ward system process. Patients undergoing ERAS in Hepatobiliary and Pancreatic Surgery Department from April to September 2019 were selected as the control group (383 cases of gallbladder surgery and 59 cases of liver surgery) , and patients admitted to the ERAS ward from April to September 2020 were selected as the experimental group (332 cases of gallbladder surgery and 72 cases of liver surgery) . The satisfaction, average length of hospitalization, hospitalization expenses and complication rate of the two groups of patients were compared, and doctors and nurses' specification implementation rate of the ERAS ward was counted.Results:The average length of hospitalization of patients with gallbladder surgery and liver surgery in the experimental group was shorter than that of the control group, and the hospitalization expenses were lower than those of the control group, and the differences were statistically significant ( P<0.01) . The complication rate (9.9%, 33/332) of patients undergoing gallbladder surgery in the experimental group was lower than that (16.7%, 64/383) in the control group, and the difference was statistically significant ( P<0.01) . The satisfaction of patients in the experimental group was higher than that in the control group, and the difference was statistically significant ( P<0.01) . The specification implementation rate of doctors and nurses was 96.7% (58/60) . Conclusions:The ERAS ward is based on the scientific supervision of staff, stuff, structure space and systems according to the concept of 4S management model, which is conducive to the comprehensive and standardized implementation of ERAS treatment and nursing, improves patient clinical outcomes and increases patient satisfaction.

The patient, an 84-year-old man, was admitted to the hospital with "low back pain with limitation of movement for more than half a year". Admission examination: mild kyphotic deformity of the spine, significant tenderness and percussion pain in the lower back, bilateral lower limb muscle strength graded 5, normal skin sensation. Lumbar MRI and CT revealed a compressive fracture of the L 4 vertebra. Dual-energy X-ray absorptiometry (DEXA) indicated a bone mineral density T-score of -2.6, suggesting osteoporosis. Admission diagnosis: osteoporotic compressive fracture of the L 4 vertebra. The patient underwent thorough examinations to exclude surgical contraindications. On the fourth day of admission, the patient underwent percutaneous vertebroplasty of the L 4 vertebra. At the end of the operation, the patient became unresponsive, with a blood pressure drop to 94/63 mmHg and oxygen saturation falling to 80%. Cranial CT showed multiple punctate gas density shadows within the brain. Lumbar CT revealed gas accumulation in the soft tissue adjacent to the lumbar spinous processes, localized intraductal gas, and punctate gas density shadows within the vessels in both groin areas. The diagnosis was intracranial arterial gas embolism. The patient's condition deteriorated further, with loss of consciousness, neck stiffness, increased muscle tone of both lower limbs, and positive Babinski's sign on both sides. Symptomatic treatments included brain protection, maintaining cerebral perfusion, and improving collateral cerebral circulation, but the patient did not regain consciousness. The patient developed a pulmonary infection one month postoperatively and died three months postoperatively due to respiratory failure. This case highlights the potential risk of gas embolism during vertebroplasty. Measures to reduce such complications should be implemented, such as minimizing the duration of venous blood-air contact, pre-filling the cannula with saline to reduce the venous blood-air interface, and appropriately increasing venous pressure to reduce the risk of gas entry. It is recommended to use smaller diameter catheters. For patients with pre-existing cardiac conditions or elderly patients, preoperative cardiac Doppler ultrasound should be performed to exclude anatomical abnormalities such as patent foramen ovale.
