INTERFASCIAL PLANE BLOCKS IN OBSTETRIC AND GYNECOLOGIC SURGERY.

Introduction: Interfascial plane blocks (IPB) are truncal blocks with local anesthetic injected into space between two muscle layers. IPBs are easy to learn, simple to perform, provide satisfactory analgesia up to 24 hours, having a minimal risk of complications. Methods: We present a retrospective analysis of the patients who had IPB as a part of postoperative pain management plan following either CD or hysterectomy in Leskovac General Hospital, Serbia during the period April 2017 - February 2022. Results: We had 131 patients who had IPB perioperatively. Bilateral QLB type 1 was performed in 53 patients after CD and in 68 patients after hysterectomy. Bilateral ESPB T10-11 was done following one CD case and in 9 patients before hysterectomy. Patients had both acetaminophen and nonsteroidal anti-inflammatory drug for postoperative pain control. Decreased usage of fentanyl and sevoflurane was noticed in the cases where IPB was performed preoperatively. Almost all patients had well-controlled pain, and were very satisfied with pain score of 0-4/10 at numeric rating scale during 24 hours after surgery, with no opioid use. There were no complications regarding block performance. Conclusion: QLB and ESPB have great potential to improve and facilitate postoperative pain management in obstetric and gynecologic surgery.

Post Partum Death in a Patient Diagnosed With COVID-19.

Background: There are few case reports describing maternal mortality and intensive care of the pregnant patient with COVID-19 infection. Case: A 27-year-old patient at 34 weeks of gestation was admitted for the evaluation of cough, fever, tachypnea, and oligohydramnios. The day of admission she underwent cesarean delivery for a non-reassuring fetal heart rate tracing. Over the next 6 days her clinical condition deteriorated, she developed multi organ system failure, and died despite aggressive supportive care. Conclusion: Although mortality related to COVID-19 in pregnancy has been rarely reported to date, we describe a case of progressive clinical deterioration postpartum despite aggressive supportive care. Management strategies specific for pregnant women have not been developed. In timing delivery, the obstetrician must consider the possibility that the inflammatory response associated with CD may increase the risk for multiorgan system failure in parturients with COVID-19 while recognizing that risks to the fetus may be higher in patients with COVID-19 than in other critically ill parturients. Vertical transmission of infection to the neonate did not occur in our case and has not been demonstrated in other pregnancies with COVID-19 disease.

A Review of the Quadratus Lumborum Block and ERAS.

The use of truncal nerve blocks has been described since 2001. Since then, there have been many studies trying to understand the ideal clinical scenarios for its use. Since 2001, the transversus abdominis plane block has evolved in many ways including from landmark based technique to ultrasound guided and more recently, into the quadratus lumborum (QL) block. Its anatomical placement, concentration of local anesthetic, volume of local anesthetic, and anatomic placement have all been raised as clinical questions. This article will discuss the literature of the QL block in an effort to understand how it is best used in a variety of clinical scenarios.
