Brief Summary

This study is a further observation and follow-up of the patients enrolled in the registration number ChiCTR230007164430 to further evaluate the effect of long-term infusion of esketamine and lidocaine on postoperative chronic pain, long-term quality of life and survival rate in patients undergoing hepatectomy.

Detailed Description

This study is a further observation and follow-up of the patients enrolled in the registration number ChiCTR230007164430 to further evaluate the effect of long term infusion of esketamine and lidocaine on postoperative chronic pain, long-term quality of life and survival rate in patients undergoing hepatectomy. 304 patients with primary liver cancer who meet the inclusion criteria were included. According to the random number, the patients were divided into esketamine-lidocaine group and conventional analgesia group. In the esketamine-lidocaine group, patients received esketamine (0.25 mg/kg) and lidocaine (1.5 mg/kg) at the induction of anesthesia, followed by the continuous infusion of esketamine (0.02 mg/kg∙h) and lidocaine (1.5 mg/kg∙h) until the end of surgery. Postoperatively, the patients used 2 pumps. One pump delivered a fixed-rate infusion of lidocaine at 1.0 mg.kg-1.h-1 and esketamine at 0.02 mg.kg-1.h-1 infusion for 72 hours. Another PCIA device contained sufentanil 2 ug/kg, granisetron 12 mg diluted to 200 mL in 0.9 % normal saline. In the placebo group, the same volume of normal saline instead of lidocaine and esketamine will be administered. Numeric rating scale (NRS) is used to evaluate pain at rest and light activities at postoperative 24, 48, 72 hours. Follow-up after discharge includes chronic pain, the impact of chronic pain on quality of life, the relapse-free survival and overall survival from postoperative 3 months to 5 years.

Study Groups

Esketamine-lidocaine group

Patients received esketamine (0.25 mg/kg) and lidocaine (1.5 mg/kg) at the induction of anesthesia, followed by the continuous infusion of esketamine (0.02 mg/kg∙h) and lidocaine (1.5 mg/kg∙h) until the end of surgery. Postoperatively, the patients received two pumps. One pump delivered a fixed-rate infusion of lidocaine at 1.0 mg.kg-1.h-1 and esketamine at 0.02 mg.kg-1.h-1 infusion for 72 hours. Another PCIA device contained sufentanil 2 ug/kg, granisetron 12 mg diluted to 200 mL in 0.9 % normal saline.

Group Type: EXPERIMENTAL

Esketamine-lidocaine group

Intervention Type: DRUG

In the esketamine-lidocaine group, patients received esketamine (0.25 mg/kg) and lidocaine (1.5 mg/kg) at the induction of anesthesia, followed by the continuous infusion of esketamine (0.02 mg/kg∙h) and lidocaine (1.5 mg/kg∙h) until the end of surgery. Postoperatively, the patients received two pumps. One pump delivered a fixed-rate infusion of lidocaine at 1.0 mg.kg-1.h-1 and esketamine at 0.02 mg.kg-1.h-1 infusion for 72 hours. Another PCIA device contained sufentanil 2 ug/kg, granisetron 12 mg diluted to 200 mL in 0.9 % normal saline.

Placebo group

Patients received the same volume of normal saline instead of lidocaine and esketamine until the end of surgery. Postoperatively, the patients received two pumps. One pump was the same volume of normal saline instead of lidocaine and esketamine. Another PCIA device contained sufentanil 2 ug/kg, granisetron 12 mg diluted to 200 mL in 0.9 % normal saline.

Group Type: PLACEBO_COMPARATOR

Placebo group

Intervention Type: OTHER

In the conventional analgesia group, patients received the same volume of normal saline instead of lidocaine and esketamine until the end of surgery. Postoperatively, the paitents received two pumps. One pump was the same volume of normal saline instead of lidocaine and esketamine. Another PCIA device contained sufentanil 2 ug/kg, granisetron 12 mg diluted to 200 mL in 0.9 % normal saline.

Postoperatively, the patients received two pumps. One pump delivered a fixed-rate infusion of lidocaine at 1.0 mg.kg-1.h-1 and esketamine at 0.02 mg.kg-1.h-1 infusion for 72 hours. Another PCIA device contained sufentanil 2 ug/kg, granisetron 12 mg diluted to 200 mL in 0.9 % normal saline.

Intervention Type: DRUG

Placebo group

In the conventional analgesia group, patients received the same volume of normal saline instead of lidocaine and esketamine until the end of surgery. Postoperatively, the paitents received two pumps. One pump was the same volume of normal saline instead of lidocaine and esketamine. Another PCIA device contained sufentanil 2 ug/kg, granisetron 12 mg diluted to 200 mL in 0.9 % normal saline.
