- Brief Summary
Male infant circumcision is a frequently performed, but painful procedure. A variety of methods, both systemic and locoregional, have been developed to overcome postoperative pain after circumcision. It has been shown that local anesthetic techniques are more effective than opioids. Especially caudal block and dorsal penile nerve block provide adequate early analgesia (up to 2 hours) after circumcision.
Although the postoperative analgesic effects of CB and DPNB have been evaluated in literature before, these two techniques that are commonly used in circumcision surgery in the paediatric population, have not yet been compared when using DXM as an adjuvant in both methods. On the other hand, to our knowledge there is no evidence that indicates any other advantage than a reduced incidence in PONV when it comes to circumcision patients having a DNPB with IV DXM.
Therefore, this study aims to evaluate the analgesic effect of CB using levobupivacain with IV DXM compared to DPNB using levobupivacain with IV DXM and DPNB without IV DXM. It is questioned whether the addition of IV DXM to the DPNB might shift our standard of care towards a locoregional technique avoiding the neuraxial route, without losing the analgesic quality of the combination of a CB with IV DXM.
- Detailed Description
All male infant patients, between ≥ 1 and \< 7 years of age, undergoing circumcision will be randomized in a 1:1:1 ratio to the
1. Caudal blockade group with dexamethasone or;
2. Dorsal penile nerve block group with dexamethasone or;
3. Dorsal penile nerve block group withouth dexamethasone.
After induction of anaesthesia the allocated locoregional anaesthesia technique will be performed.
For the caudal blockade group levobupivacaine 0,25% 0,5ml/kg will be administered through the hiatus sacralis lege artis. After performing the caudal blocakde, IV administration of dexamethasone 0.5 mg/kg (max. 5 mg).
For the dorsal penile nerve block levobupivacaine 0,5% 0,1ml/kg will be administered on each side of the midline as described in Hadzic's textbook of regional anaesthesia. After performing of the dorsal penile nerve block, IV administration of dexamethasone 0.5 mg/kg (max. 5 mg) in patients in the dorsal penile nerve block group with dexamethasone .
IV administration of diclofenac 1mg/kg and paracetamol 15mg/kg for both groups. If heart rate raises with \>20% from baseline within 2 minutes after incision, administration of sufentanyl (0,1µg/kg IV) is necessary.
Pain scores are evaluated after awakening at PACU, measured by the FLACC scale, at following timepoints: 30 minutes, 1 hour, 2 hours, 6 hours, 12 hours and 24 hours postoperative. During recovery stay till hospital discharge pain scores will be registered by the study nurse. Registration of pain scores after hospital discharge (till 24 hours postoperative) will be performed by (one of) the parents of the patient, who will be educated how to use the FLACC scale by the study nurse. A follow up phone call will be performed by the study nurse to collect the remaining pain scores starting from hospital discharge.
Pain medication exists of standard administration of paracetamol PO 15mg/kg every 6 hours (starting 6 hours after the intraoperative administered dose) and ibuprofen PO 10mg/kg every 8 hours (starting 8 hours after the intraoperative administered diclofenac).
When FLACC score remains above 3, rescue pain medication will be administered during hospital stay. Rescue pain medication consists of tramadol intravenously (PACU) or oral drops (ward) 1mg/kg and can be repeated at maximum every 6 hours.
