Surgical Remove of Hemorrhoids Clinical Trial
Official title:
Assessment of the Analgesic Efficacy of Morphine Chloride in Addition to a Low Dose Solution of Spinal Anaesthetic in Hemorrhoidectomy Compared to a Standard Dose of Spinal Local Anaesthetic. Simple Blind, Randomized, With Blinded Evaluation by Third Parties Clinical Trial.
A single blind, randomized, with blinded evaluation by third parties clinical trial is
carried out to assess the analgesic efficay of the addition of morphine chloride to a low
dose solution of spinal local anaesthetic compared to a standard dose spinal anaesthetic in
the haemorrhoid surgery.
The objective of this clinical trial is to assess if the experimental treatment is as
efficacy as the standard treatment in the anesthetic and analgesic effects with less side
effects, greater and earlier mobility after surgery and shortened the hospitalization.

Primary | Measurement of Time to Start the Anaesthetic Effect | To compare whether the addition of morphine chloride to a low dose intradural solution of the local anaesthetic bupivacaine is as effective as an administration of a single dose of bupivacaine. | First 20 minutes between administration and beginning of surgery | No |
Primary | Measurement of the Analgesic Effect After Surgery by VAS From 0 to 10, Where 0 is no Pain and 10 is the Worst Pain Imaginable. | To compare whether the addition of morphine chloride to a low dose solution of bupivacaine and improves the analgesic treatment than a single administration of bupivacaine. | Up to 72 hours from the end of the surgery in the hospital stay and during the next 7 days at home, after discharge | No |
Secondary | Greater and Earlier Mobilization Measured by Bromage Scale. | To assess whether the administration of morphine chloride in addition to a low dose solution of local intradural anaesthetic (bupivacaine) improves the mobilization of the patients after surgery more than the single intradural administration of bupivacaine. Total Score in the Bromage Scale goes from 1 to 5, where: 1: complete motor blocking - 2: capable to move the feet - 3: moves the feet and bends the knee - 4: raise the leg straight more or less than 30 degrees but no against resistance - 5: raise the leg straight more than 30 degrees against resistance (no motor blocking) |
During the first 24 hours after surgery and at the entry and exit of the resuscitation unit | Yes |
Secondary | Number of Adverse Events | To assess if the experimental treatment causes less, equal or more adverse events than the comparator treatment. | Up to 72 hours from the intervention and the hopitalary stay and during the next 7 days after discharge | Yes |
Secondary | Time of Hospitalization | To see if the hospitalization time is shortened or not by the experimental treatment. | Up to 72 hours after the intervention | Yes |
