Interest in Clonidine in Association With Levobupivacaine Performing a Pudendal Block in Proctological Surgery: Pilot Study, Prospective

Proctological surgery represents a short duration surgery performed in ambulatory, which causes significant post-operative pain.

Post-operative pain resulting from proctological surgery is greater than 5 on the Visual Analog Scale (VAS) within the first 24 hours and it revives during the first defecation.

The ideal pain management procedures are based on the multimodal analgesia model, based in turn on the combination of products and / or techniques to improve the quality of analgesia, reduce the side effects linked to the use of opioids, reduce responses to surgical stress, reduce postoperative recovery and allow rapid rehabilitation of the patient.

The aim of our study is to investigate whether clonidine combined with levobupivacaine in the pudendal block reduce the total consumption of opioids in proctological surgery.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
EXPERIMENTAL: Group Clonidine
Group Clonidine will benefit from the pudendal block realised with 10 ml of 0.25% levobupivacaine and 75 µg of clonidine per side.
75 µg (0.5mL) per injection site
Other Names:

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Total Dose of Opioids consumed in the intraoperative period
Time Frame: up to 24 hours post-surgery
Total consumption of sufentanyl during the intraoperative period (in micrograms). The administration of sufentanyl depends on the change of physiological parameters (augmentation of 20% of blood pressure and/or cardiac frequency).
up to 24 hours post-surgery

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Total Dose of tramadol consumed in the recovery room
Time Frame: up to 24 hours post-surgery
In the recovery room, dose of tramadol (in milligrams, intravenous administration). The administration of tramadol depends on Visual Analogic Pain Score (VAS>4) (scale = 0 no pain; 10 = worst pain imaginable)
up to 24 hours post-surgery
Total consumption of tramadol in post-operative period
Time Frame: up to 24 hours post-surgery

Total consumption of tramadol from the exit of the recovery room to the day after the surgery based on Visual Analogic Pain Score >4 (scale = 0 no pain; 10 = worst pain imaginable).

Tramadol (dose in milligrams, oral administration)

up to 24 hours post-surgery
Need for tramadol administration per patient during the first 24 hours
Time Frame: up to 24 hours post-surgery
Number of Tramadol dose requested by the patient during the first 24 hours
up to 24 hours post-surgery
Total Dose of piritramide consumed in the recovery room
Time Frame: up to 24 hours post-surgery
In the recovery room, dose of piritramide (in milligrams, intravenous administration). The administration of piritramide depends on Visual Analogic Pain Score (VAS>4) (scale = 0 no pain; 10 = worst pain imaginable)
up to 24 hours post-surgery
Need for Piritramid administration per patient during the hospitalization in Post Anesthesia Care Unit (PACU)
Time Frame: during the hospitalization in Post Anesthesia Care Unit (PACU)
Number of Piritramid dose requested by the patient during the hospitalization in Post Anesthesia Care Unit (PACU)
during the hospitalization in Post Anesthesia Care Unit (PACU)
Total consumption of paracetamol in post-operative period
Time Frame: up to 24 hours post-surgery
Total consumption of paracetamol from the exit of the recovery room to the day after the surgery based on Visual Analogic Pain Score >4 (scale = 0 no pain; 10 = worst pain imaginable). Paracetamol (dose in grams, oral administration)
up to 24 hours post-surgery
Total consumption of diclofenac in post-operative period
Time Frame: up to 24 hours post-surgery

Total consumption of diclofenac from the exit of the recovery room to the day after the surgery based on Visual Analogic Pain Score >4 (scale = 0 no pain; 10 = worst pain imaginable).

Diclofenac (dose in milligrams, oral administration)

up to 24 hours post-surgery
Time before First Use of Rescue Analgesic
Time Frame: up to 24 hours post-surgery
Time between the completion of the block and the first post-operative administration of rescue analgesics (Tramadol and/or Piritramide on request)
up to 24 hours post-surgery
Post-operative Pain as assessed by Visual Analog Scale
Time Frame: up to 24 hours post-surgery
Post-operative Pain levels will be determined every 15 minutes in the recovery room, then every hour until discharge and on Day 1 at home; Visual Analog pain score (scale = 0 no pain; 10= worst pain imaginable)
up to 24 hours post-surgery
Patient satisfaction
Time Frame: up to 24 hours post-surgery
Level of satisfaction assessed on a 5-point scale (from 1 to 5): 1 not satisfied, 2 not very satisfied, 3 moderately satisfied, 4 satisfied, 5 very satisfied.
up to 24 hours post-surgery
