A Novel Analgesic Method for Postoperative Pain Relief After Cesarean Section: Intraoperative Superior Hypogastric Block

Postoperative Pain Clinical Trial

Official title: A Novel Analgesic Method for Postoperative Pain Relief After Cesarean Section: Intraoperative Superior Hypogastric Block

Status Completed

Clinical Trial Summary

Cesarean section is the most common inpatient surgical procedure in the United States with 1.3 million cesarean deliveries performed in 2015. Cesarean section frequency is increasing rapidly in worldwide, especially in middle and high income countries.

Postoperative pain is an expected outcome for patients following surgical procedures. Inadequate pain relief is still a common problem among hospitalized patients. Cesarean section ranked ninth for pain severity among 179 different surgical procedures.

Multimodal pain therapy has been suggested for postoperative pain management after cesarean delivery. The most commonly used modalities are systemic administration of opioids, either by intramuscular injection or IV by patient-controlled analgesia, and neuraxial injection of opioid as part of a regional anesthetic for cesarean delivery. These techniques have specific advantages and disadvantages.

Superior hypogastric plexus blockade (SHB) has been shown an effective method for pain relıef after gynecologic procedures, it has been shown that SHP can be easily performed intraoperatively during hysterectomy procedure In this study, we aimed to investigate the efficacy of SHB performed intraoperatively for postoperative pain relief after cesarean section. To our knowledge, this is the first study to use SHB intraoperatively for pain relief after cesarean section in the literature.

Clinical Trial Description

Cesarean section is a life-saving surgical operation performed during pregnancy and labor. It is the most common inpatient surgical procedure in the United States with 1.3 million cesarean deliveries performed in 2015. Cesarean section frequency is increasing rapidly in worldwide, especially in middle and high income countries.

Postoperative pain is an expected outcome for patients following surgical procedures. Inadequate pain relief is still a common problem among hospitalized patients. A number of surveys report that 30%-70% of surgical patients experience moderate to severe pain (Breivik) At least 10.9% of women experience severe pain within 24 h after cesarean section. An analysis of 50523 patients from 105 hospitals questioning pain intensity on the first postoperative day revealed that cesarean section ranked ninth for pain severity among 179 different surgical procedures.

In this regard, multimodal pain therapy has been suggested for postoperative pain management after cesarean delivery. It requires the use of a combination of drugs with different mechanisms of action, and aims at achieving optimal analgesia through additive or synergistic drug action with small doses of opiates and decreased side effects. The most commonly used modalities are systemic administration of opioids, either by intramuscular injection or IV by patient-controlled analgesia, and neuraxial injection of opioid as part of a regional anesthetic for cesarean delivery. These techniques have specific advantages and disadvantages.

Recently, superior hypogastric plexus blockade (SHB) has been shown an effective method for pain relıef after gynecologic procedures, i.e. hysterectomy (kaynak). The superior hypogastric plexus (SHP) is a retroperitoneal structure located bilaterally at the level of the lower third of the fifth lumbar vertebral body and upper third of the first sacral vertebral body at the sacral promontory in which it is most accessible to block for pelvic pain relief. Besides it can be performed either by fluoroscopy-guided, ultrasound (US)-guided, or CT-guided techniques, it has been shown that SHP can be easily performed intraoperatively during hysterectomy procedure ().

In this study, we aimed to investigate the efficacy of SHB performed intraoperatively for postoperative pain relief after cesarean section. To our knowledge, this is the first study to use SHB intraoperatively for pain relief after cesarean section in the literature. ;
