Effects of Analgesics in Cesarean Section Elective

Phase 4
Completed
Conditions
Anesthesia; Functional
Interventions
Drug: Hyperbaric bupivacaine+Sufentanil
Drug: Hyperbaric bupivacaine+Morphine
Registration Number
NCT03386630
Lead Sponsor
Fundación Pública Andaluza Progreso y Salud
Brief Summary

Two approved treatments for spinal anesthesia will be compared in women undergoing cesarean section.

It is usual to perform cesarean sections using spinal anesthesia with a local anesthetic (bupivacaine) plus some opioid, such as sufentanil or morphine. Both have been shown to decrease postoperative pain, but we try to check if one brings more benefit than the other.

Hyperbaric bupivacaine+SufentanilHyperbaric bupivacaine+SufentanilTo evaluate in spinal anesthesia for elective cesarean section what association of hyperbaric bupivacaine 0.5% (0.06 mg Cm-1 in height) plus opioid: sufentanil (5 mcg)
Hyperbaric bupivacaine+morphineHyperbaric bupivacaine+MorphineTo evaluate in spinal anesthesia for elective cesarean section what association of hyperbaric bupivacaine 0.5% (0.06 mg Cm-1 in height) plus opioid: morphine (0,01 mg)
Primary Outcome Measures
NameTimeMethod
To evaluate the time it takes the patients administer a first analgesic bolus of morphine intravenous personally after subarachnoid anesthesia in elective cesarean section.3 days

To evaluate in spinal anesthesia for elective cesarean section what association of hyperbaric bupivacaine plus opioid: sufentanil or morphine, produces a longer time for the patient to administer a first analgesic bolus of intravenous morphine.

Secondary Outcome Measures
NameTimeMethod
Lower intravenous morphine consumption24 hours after surgery
Mother´s side effects with respect to hemodynamic alteration, nausea, vomits, pruritus, tremor, urinary retention, sedation, respiratory depression, headaches, motor deficits, permanent sensory or autonomic deficits.At intraoperative
Beginning of sitting and standingAt 48 hours after surgery
Levels of minor pain verbal scalesAt 3, 6, 12 and 24 hours after surgery

The measure is based in EVA (Escala visual analógica del dolor) scale. EVA scale allows to measure the pain intensity that the patient describes with the maximum reproducibility among the observers.

1. Mild pain if the patient scores the pain as less than 3.

2. Moderate pain if the assessment is between 4 and 7.

3. Severe pain if the assessment is equal to or greater than 8.
