About
Pain is considered to be subjective, however in children it is believed to be felt rather than expressed, because they often depend on the caregiver for their safety and well-being.
There is significant pain after thoracotomy surgery because of pleural and muscular damage, ribcage disruption, and intercostal nerve damage during surgery, which if not effectively managed, it will lead to various systemic complications; pulmonary (atelectasis, pneumonia, and stasis of bronchial secretions), cardiovascular (increased oxygen consumption and tachycardia), musculoskeletal (muscle weakness), increased neuro-hormonal response and prolonged hospital stay. So adequate and sufficient post-operative analgesia for paediatric patients is mandatory.
The use of highly potent opioids for paediatric cardiac anaesthesia has gained widespread popularity during the last 20 years.In addition to the important advantage of hemodynamic stability, the large-dose opioid-based anaesthetic techniques also blunt the stress response, However, large doses can cause oversedation, respiratory depression, and prolonged mechanical ventilation after surgery.
Erector Spinae Plane Block (ESPB), recently developed by Forero et al, is a novel technique in management of thoracic neuropathic pain guided by ultrasound. It became popular because it is much safer and easily administered than other alternative regional techniques as thoracic paravertebral and thoracic epidural block.
To our knowledge, Erector Spinae Plane Block (ESPB) performed in aortic coarcitectomy operations has not been investigated yet.This has encouraged the performance of the present study.
Full description
Our study will be designed to estimate and compare the analgesic effect of single shot erector spinae plane block in pediatric patients undergoing aortic coarcitectomy via thoracotomy incision versus fentanyl infusion as the control group. Our primary outcome will be the total dose of intraoperative fentanyl bouluses.
Randomization will be achieved by using an online random number generator. Patient codes will be placed into sequentially numbered sealed opaque envelopes by a research assistant who is not involved in the study. A medical personnel not involved in patient management will be responsible for opening the envelope and give the instructions contained within each envelope to the anesthesiologist who is expert in doing the ESPB in patients included within the block group. this expert anaesthesiologist will not be involved in collecting data but another anaesthesia doctor will be responsible for patient management and collecting the intraoperative and postoperative data.
The study will be conducted in the pediatric cardiothoracic operation theatre in Abu El Reesh Pediatric Hospital -Cairo University on 28 pediatric patients aged 3 months-12 months, ASA III undergoing aortic coarcitectomy (with thoracotomy incision).
All patients will attend at the pre- anesthesia room with their parents 1 hour before the procedure after taking approval of research ethical comittee and informed consent.
Detailed history from the parents will be taken followed by a full and detailed clinical examination of the child then all investigations including CBC, coagulation profile, liver enzymes, kidney function tests, Chest x-ray ,echocardiography and blood grouping will be checked.
ECG, pulse oximetry and non-invasive blood pressure will be applied to all patients. All patients will be premedicated by intramuscular midazolam 2mg/Kg and atropine 0.2 mg/Kg 20 minutes before induction of anesthesia.
Anesthesia will be induced in all patients by sevoflurane 5% in 100% O2 followed by Placement of peripheral I.V cannula and IV administration of fentanyl (1-2µg/kg). Oral endotracheal intubation will be facilitated by IV atracurium 0.5 mg/kg and then capnogram will be connected to monitor End-tidal CO2 and muscle relaxation will be maintained by atracurium infusion in a dose of 0.5 mg/ kg/ hr.
All patients will be mechanically ventilated using pressure controlled mode with FiO2 50%, positive end expiratory pressure (PEEP) 5 cmH2O,I: E ratio of 1:2,peak inspiratory pressure (PIP) will be set to deliver a tidal volume of 6-8 ml/kg and respiratory rate will be 15 to 35 cycle / minute according to the age. our aim is to keep end tidal CO2 between 30-40 mmHg.
Sevoflurane will be used for maintenance of anaesthesia and its MAC will be determined by using bispectoral index (targeting 40-60) to standardize the depth of anaesthesia.
After insertion of a central venous catheter and an arterial cannula , nasopharyngeal temperature probe will be placed and the patient's position will be changed from supine to right lateral position.
