Detailed Description
Open Renal surgeries (pyeloplasty and nephrectomy) is associated with significant postoperative pain. Adequate postoperative analgesia is important to allow for early mobilization and discharge of the patients .Systemic opioids are usually not sufficient for pain control after renal surgeries in children. The use of opioid in pediatrics has many side effects such as somnolence, vomiting, and up to respiratory depression.
Neuraxial analgesia is usually required in these operations in combination with general anesthesia. Neuraxial analgesia decreases morbidity, mortality, opiate exposure, shortens post anesthesia recovery room time and hospital stay. However, it is usually associated with many complications as urinary retention and excessive motor block.
Caudal block is the most commonly used neuraxial anesthesia in pediatric patients. It can be used for analgesia in different renal surgeries providing adequate pain relief in the post- operative period .
Paediatric regional anaesthesia (PRA) is one of the most valuable and safe tools to treat perioperative pain and is an essential part of modern anaesthetic practice. It offers many advantages to both the patient and the hospital. It provides excellent pain relief and allows caregivers to use multimodal analgesic techniques and decrease the use of opioids without the complications of neuraxial anesthesia. Considerable progress has been made in the practice of PRA over the past few years including availability of information on safety and incorporation of ultrasound guidance. Novel regional anaesthesia (RA) techniques, especially the anterolateral and the posterolateral trunk blocks, show promise .
The erector spinae plane block (ESPB), one of the posterolateral trunk blocks, was first described by Forero et al. in 2016 and has been used by many anaesthesiologists for perioperative pain relief 4. Its mechanism of action is spreading of local anesthetic into multiple paravertebral spaces after injection into the interfascial space between the transverse process of the vertebrae and the erector spinae muscle. It can be used for postoperative analgesia for longer period and decrease the use of opioids with less complications in several pediatric surgeries including nephrectomy and pyeloplasty.
For this reason, ESPB efficacy will be compared to the caudal block efficacy seeking for a simple, safe and effective regional analgesic technique for renal surgeries in children.
Electrical Cardiometry is a method for the non-invasive determination of stroke volume (SV), cardiac output (CO), stroke volume variation (SVV) and other hemodynamic parameters in adults, children, and neonates and it has been validated against "gold standard" methods such as thermodilution. Several potential mechanisms have been suggested for the action of the ESPB such as paravertebral spread as well as epidural spread of local anesthetic. These mechanisms raise the concern of the possible negative hemodynamic consequences of the ESPB which were not properly investigated .
