Procedural Sedation for Pediatric Patients With Spinal Muscular Atrophy

Study Overview
=================
Brief Summary
-----------------
Background and Aim: Spinal muscular atrophy (SMA) is a neuromuscular disease characterized by progressive symmetrical weakness and atrophy of proximal muscles causing from degeneration of anterior horn cells of spinal cord. Nusinersen must be administered intrathecally and this treatment is specially for spinal muscular atrophy. Procedural sedation is commonly enough for intrathecal treatment in children. In this retrospective study, the investigators aimed to present our experience in procedural sedation for the intrathecal treatment of patients with SMA 1,2 and 3 in our hospital.

Detailed Description
-----------------
Design: This research is a retrospective obsevational study. Methods: After approval Institutional Review Board, data from anesthesia charts and electronic medical records of 14 patients with SMA type I, II and III who underwent procedural sedation,such as; the demographics data of the patients (age, gender, weight, American Society of Anesthesiologist (ASA) Physical Status), which anesthetic agent was used and their doeses, during of anesthesia, presence of scoliosis, by whom the procedure was performed etc. was reviewed. All our patients with SMA type II and III who underwent intrathecal treatment are given sedation with different combination of anesthetic agent. Due to peripheral intravenous line was placed previously, intravenous induction was performed in all of our patients For procedural sedation, anesthesiologists used different combination of midazolam, ketamine, propofol, fentanyl or remifentanyl, depending on the patient's requirement. They were oxygenated with a face mask or nasal cannula while their spontaneous breathing continues. All patients were recovered in the recovery room. Statistical analysis: The data were analyzed by using SPSS Statistics Software (SPSS 24, Chicago, IL, USA) Descriptive statistics were used in this study. Mean and standart deviation were calculated for Age (year), Weight (kilogram), Midazolam Dose (mg/kg), Fentanyl Dose (mcg/kg), Remifentanyl Dose (mcg/kg), Propofol Dose (mg/kg), Ketamine Dose (mg/kg) and Length of Stay in Recovery Room (minute) and frequency analysis were made for the number of intervention.
