Pre-emptive Scalp Infiltration With Dexamethasone Plus Ropivacaine for Postoperative Pain After Craniotomy

February 15, 2020 updated by: Fang Luo, Beijing Tiantan Hospital

Pre-emptive Scalp Infiltration With Dexamethasone Plus Ropivacaine vs. Ropivacaine for Relief of Postoperative Pain After Craniotomy in Adults

A majority of patients would suffer from moderate-to-severe postoperative pain after undergoing craniotomy. As a result, adequate pain control is essential for patients' prognosis and their postoperative life quality. Although opioids administration is regarded as the first-line analgesic for post-craniotomy pain management, it may be associated with delayed awakening, respiratory depression, hypercarbia and it may interfere with the neurologic examination. For the avoidance of side-effects of systemic opioids, local anesthetics administered around the incision have been performed clinically. However, some studies revealed that the analgesic effect of local anesthetics was not unsatisfactory due to its short pain relief duration. As is reported that postoperative pain of craniotomy is mainly caused by skin incision and reflection of muscles, preventing the liberation of inflammatory mediators around the incision seems to be more effective than simply blocking nerve conduction. Thus, Investigators suppose that pre-emptive scalp infiltration with steroid (dexamethasone) plus local anesthetic (ropivacaine) could relieve postoperative pain after craniotomy in adults.

Participant Group / Arm
Intervention / Treatment
Experimental: Dexamethasone plus Ropivacaine group
Participates received peri-incisional scalp infiltration of a miscible liquid of dexamethasone and ropivacaine. The local infiltration miscible liquid containing 0.33mg dexamethasone and 5mg ropivacaine per milliliter
Intervention in this study will be peri-incisional scalp infiltration with dexamethasone, ropivacaine and normal saline miscible liquids for participants who will undergo elective craniotomy. The local infiltration solution containing 0.33mg dexamethasone and 5mg ropivacaine per milliliter will be infiltrated along the incision and throughout the entire thickness of the scalp before skin incision. The volume of local infiltration solution will be decided by surgeons according to the cut length, and the capacity of the solution will be recorded by investigator.
Active Comparator: Ropivacaine group
Participates received peri-incisional scalp infiltration of 5mg/mL ropivacaine.
Intervention in this study will be peri-incisional scalp infiltration with ropivacaine for participants who will undergo elective craniotomy. The local infiltration solution containing 5mg ropivacaine per milliliter will be infiltrated along the incision and throughout the entire thickness of the scalp before skin incision.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Cumulative sufentanil consumption within 48 hours postoperatively
Time Frame: Within 48 hours after the operation
All participates will receive an electronic intravenous patient-controlled analgesia (PCA) device in which the bolus dose of sufentanil will be set as 2 μg with a lockout interval of 10 min and the maximum dose will be limited as 8 μg per hour. If the participates feel inadequate analgesia after 5 times of sufentanil bolus, the bolus dose will be increased to 3 μg and the maximum dose will be increased to 12 μg per hour.

Quality of life will be measured using the World Health Organisation QoL-BREF (WHOQOL-BREF) questionnaire. The WHOQOL-BREF is a abbreviated version of the WHOQOL-100 assessment. WHOQOL-BREF is a self-report questionnaire that contains 26 items and addresses 4 QOL domains: physical health (7 items), psychological health (6 items), social relationships (3 items) and environment (8 items). Two other items measure overall QOL and general health. Each domain's mean score can range between 4 and 20 and a higher score indicates a higher quality of life. The mean score of items within each domain is used to calculate the domain score. A transformation method converts domain scores to a 0-100 scale.
