Clinical signs and prognosis are strongly influenced by peak ammonia levels.

We observed the following complications: intraoperative hyperglycemia in one case, postoperative vomiting in eight cases, and slightly increased postoperative ammonia levels (54, 59, and 69\u00a0\u00b5mol\/L) with normal preoperative levels in three cases without associated metabolic decompensation. There were two cases of perioperative hyperammonemia (72 and 69\u00a0\u00b5mol\/L) secondary to preoperative metabolic decompensation (137 and 92\u00a0\u00b5mol\/L) with the levels progressively dropping and normalizing in the first 24\u201048\u00a0hours, respectively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Procedures under anesthesia on pediatric patients with urea cycle diseases should be performed by experienced multidisciplinary teams at specialized centers. Perioperative management focused on avoiding catabolism (especially during fasting) and monitoring signs associated with metabolic decompensation to allow for its early treatment should be included in routine anesthetic techniques for children with urea cycle disorders.<\/jats:p><\/jats:sec>","DOI":"10.1111\/pan.13905","type":"journal-article","created":{"date-parts":[[2020,5,6]],"date-time":"2020-05-06T21:04:41Z","timestamp":1588799081000},"page":"780-791","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Perioperative management of children with urea cycle disorders"],"prefix":"10.1111","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2406-284X","authenticated-orcid":false,"given":"Cristina","family":"Del R\u00edo","sequence":"first","affiliation":[{"name":"Department of Pediatric Anesthesiology University Hospital 12 de Octubre Madrid Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elena","family":"Mart\u00edn\u2010Hern\u00e1ndez","sequence":"additional","affiliation":[{"name":"Unit of Mitochondrial and Inherited Metabolic Diseases Pediatric Department University Hospital 12 de Octubre Madrid Spain"},{"name":"National Reference Center European Reference Network for Hereditary Metabolic Disorders (MetabERN) Madrid Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alicia","family":"Ruiz","sequence":"additional","affiliation":[{"name":"Department of Pediatric Anesthesiology University Hospital 12 de Octubre Madrid Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pilar","family":"Quijada\u2010Fraile","sequence":"additional","affiliation":[{"name":"Unit of Mitochondrial and Inherited Metabolic Diseases Pediatric Department University Hospital 12 de Octubre Madrid Spain"},{"name":"National Reference Center European Reference Network for Hereditary Metabolic Disorders (MetabERN) Madrid Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paloma","family":"Rubio","sequence":"additional","affiliation":[{"name":"Department of Pediatric Anesthesiology University Hospital 12 de Octubre Madrid Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2020,5,25]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1186\/s13023-014-0187-4"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1186\/1750-1172-7-32"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/ped.12439"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.2147\/TCRM.S93144"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/jimd.12100"},{"key":"e_1_2_10_7_1","first-page":"380","volume-title":"Manual de Urgencias de Pediatr\u00eda.
