Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To investigate the morbidity of intestinal injury after open surgery and observe the effect of comprehensive intestinal protection strategy on postoperative intestinal complications in patients undergoing laparotomy with general anesthesia.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Perioperative intestinal injury is one of the common tissues and organs injury in surgical practice. However, there is a lack of effective means of prevention and treatment.The investigators previously found that ischemic preconditioning, IPC, and dexmedetomidine has protective effects on intestinal mucosal injury.

However, the combined effect of various factors has not been clinically validated. To explore the effect of comprehensive intestinal protection strategy on postoperative intestinal complications in patients undergoing laparotomy with general anesthesia,the investigators select the patients undergoing open surgery under general anesthesia as the study subjects and the concentration of intestinal fatty acid binding protein (I-FABP) as well as the incidence of digestive system complications in one week after operation are the main observation indexes.

control group

Tourniquet would be tied to left upper limb of Patients who undergoing laparotomy for 30 minutes after the induction of anesthesia,but put no press on it. Other processes are consistent with conventional methods.

Group Type NO_INTERVENTION

No interventions assigned to this group

intervention

1. After the anesthesia induction and before surgery,the patient's left upper limb was subjected to ischemic preconditioning.
2. At the beginning of anesthesia induction, 3 μg / kg / h of dexmedetomidine was infused and adjusted to 0.3 ug / kg / h after 10 min of infusion until 30 minutes before the end of the procedure.
3. Before the induction of anesthesia, the steel wire epidural catheter was placed in the T8-9 or T10-11 gap.

Group Type EXPERIMENTAL

Ischemic preconditioning

Intervention Type PROCEDURE

After the anesthesia induction and before surgery,the patient's left upper limb was subjected to ischemic preconditioning then patients received ischemic preconditioning.

Dexmedetomidine

Intervention Type DRUG

At the beginning of anesthesia induction, 3 ug/kg/h of dexmedetomidine was infused and adjusted to 0.3 ug/kg/h after 10 min of infusion until 30 minutes before the end of the procedure.

Patient-controlled epidural analgesia

Intervention Type PROCEDURE

Before the induction of anesthesia, the steel wire epidural catheter was placed in the T8-9 or T10-11 gap.The first volume of morphine 2mg + 0.2% ropivacaine + 0.9% saline 6ml, maintenance dose of morphine 18mg + 0.1% ropivacaine + 0.9% saline total 150ml. PCEA work with a continuous background dose of 2 ml/h with a single dose of 2ml/time, load 2ml, locking time 15min.
