Patient and operative factors associated with unanticipated intensive care admission and outcomes following posterior fossa decompressions in children: A retrospective study.

INTRODUCTION: Posterior fossa decompression for Chiari I Malformation is a common pediatric neurosurgical procedure. We sought to identify the impact of anesthesia-related intraoperative complications on unanticipated admission to the intensive care unit and outcomes following posterior fossa decompression. METHODS: Medical records of all patients <18 years who underwent surgery for Chiari I malformation between 1/1/09 and 1/31/21 at the Ann & Robert H. Lurie Children's Hospital of Chicago were included. Records were reviewed for patient characteristics, anesthesia-related intraoperative complications, postoperative complications, and surgical outcomes. The primary outcome was the incidence of unanticipated admission to the intensive care unit, and the primary variable of interest was an anesthesia-related intraoperative complication. Patient, surgical characteristics, and year of surgery were also compared between patients with and without an unanticipated admission to the intensive care unit, and a multi-variable adjusted estimate of odds of unanticipated admission to the intensive care unit admission following an anesthesia-related intraoperative complication was performed. Secondary outcomes included anesthesia factors associated with an anesthesia-related intraoperative event, and postoperative complications and surgical outcomes between patients admitted to the intensive care unit and those who were not. RESULTS: Two hundred ninety-six patients with Chiari I Malformation were identified. Clinical characteristics associated with an unanticipated admission to the intensive care unit were younger age, American Society of Anesthesiologist (ASA) physical status >2 and an anesthesia-related intraoperative complication. 29 anesthesia-related intraoperative complications were observed in 25 patients (8.4%). Two of 25 patients (8%) with an anesthesia-related intraoperative complication compared with 3 of 271 (1%) patients without anesthesia-related intraoperative complication had an unanticipated admission to the intensive care unit, odds ratio 7.8 (95% CI 1.2-48.8, p = .010). When adjusted for age, sex, ASA physical status, presenting symptoms, concomitant syringomyelia, previous decompression surgery and year of surgery, the odds ratio for an unanticipated admission to the intensive care unit following an anesthesia-related intraoperative complication was 5.9 (95% CI 0.51-59.6, p = .149). There were no differences in surgical outcomes between patients with or without an unanticipated admission to the intensive care unit. CONCLUSION: Our study demonstrates that although anesthesia-related intraoperative complications during posterior fossa decompression are infrequent, they are associated with an increased risk of an unanticipated admission to the intensive care unit.

Predictive factors for adverse outcomes in pediatric patients undergoing low-risk skin and soft tissue surgery: A database analysis of 6730 patients.

BACKGROUND: There is a paucity of data regarding risk stratification of pediatric patients presenting for low-risk skin and soft tissue surgery. AIMS: We sought to determine the incidence and independent predictors of postoperative complications and unplanned 30-day readmission in a cohort of children undergoing low-risk skin and soft tissue surgery. METHODS: The study included pediatric patients who underwent minor procedures of the skin and soft tissue at continuously enrolled American College of Surgeons National Surgical Quality Improvement Program Pediatric hospitals over a two-year period. The primary outcome was a 30-day postoperative complication composite. The secondary outcome was unplanned 30-day readmission. RESULTS: The final analysis included 6,730 patients. There were a total of 170 postoperative complications among 152 patients (2.23%) with the majority of complications being either wound-related or postoperative mechanical ventilation. The independent predictors for an increased risk of postoperative complication were American Society of Anesthesiologists classification ≥3 and nutritional deficiency. There were 41 unplanned readmissions (0.61%). The presence of a postoperative wound complication or a postoperative pulmonary complication during the index hospital stay was an independent risk factor for unplanned 30-day readmission. CONCLUSION: Pediatric patients with American Society of Anesthesiologists classification ≥3 and nutritional deficiency undergoing low-risk surgery are at risk for the development of postoperative complications. Patients who develop wound and postoperative pulmonary complications are at higher risk for unplanned 30-day readmission. Identification of these higher risk patients may allow the anesthesiologist to implement targeted therapies to minimize the likelihood of occurrence of these complications.

Neuraxial Anesthesia in Children With Ventriculoperitoneal Shunts.

Neuraxial anesthesia has been demonstrated to be safe and effective for children undergoing subumbilical surgery. There is limited evidence regarding the safety of neuraxial anesthesia in pediatric patients with a ventriculoperitoneal shunt. We evaluated a series of 25 patients with indwelling ventriculoperitoneal shunts for complications within 30 days of any procedure performed with a neuraxial technique. One patient required a ventriculoperitoneal shunt revision 5 days after a lumbar catheter placement. The neurosurgeon determined the revision to be likely unrelated to the patient's lumbar catheter. Concerns about the use of neuraxial anesthesia in patients with an indwelling ventriculoperitoneal shunt may be overstated.

Otolaryngologists' perceptions of odontogenic maxillary sinusitis.

OBJECTIVES/HYPOTHESIS: Odontogenic maxillary sinusitis (OMS) is a common cause of chronic rhinosinusitis (CRS); however, the condition is infrequently mentioned in recent rhinosinusitis guidelines and often overlooked as a cause of sinusitis by otolaryngologists, dentists, and radiologists. The goal of this survey is to assess otolaryngologists' perceptions of the incidence, diagnosis, and treatment of OMS. STUDY DESIGN: Physician survey. METHODS: Ninety-three board certified otolaryngologists in the United States completed a 17-question survey on etiologies of CRS, which also included questions on alternative diagnoses and radiologic findings to reduce respondent bias toward the survey's focus on odontogenic sinusitis. Results were compared between self-reported general otolaryngologists and rhinologists. RESULTS: Both groups recognized an odontogenic source as a common cause of maxillary sinusitis and reported treating an average of 2.9 patients per year with OMS who were initially misdiagnosed. Most otolaryngologists surveyed perceived radiologists to never or rarely report on dental pathology in their sinus computed tomography (CT) interpretation. CONCLUSIONS: Both general otolaryngologists and rhinologists recognize odontogenic sinusitis is common, although often initially misdiagnosed. With increasing awareness of OMS, we believe that otolaryngologists and radiologists will review sinus CT scans for the presence of periapical abscesses and dental pathology. The otolaryngologist should suspect an odontogenic etiology of purulent maxillary CRS in patients failing to improve with antibiotics, regardless of a negative dental workup.

Clinical aspects of odontogenic maxillary sinusitis: a case series.

BACKGROUND: The incidence of odontogenic maxillary sinusitis (OMS) is unknown. Failure to address dental pathology causing sinusitis can lead to failure of medical and surgical treatments. The purpose of this article is to present an OMS patient series. METHODS: Retrospective review of prospectively accrued patients. Sinusitis guidelines were reviewed for OMS incidence and management. The clinical aspects of OMS in 21 patients diagnosed by sinus computed tomography (CT) scan over the last 30 months were assessed. RESULTS: In our series the mean age was 53 years (range, 21-70 years), mean duration of symptoms was 2.6 years (range, 1 month to 15 years), rotten smell or bad taste was present in 10 of 21 (48%) patients, dental pain was present in 6 of 21 (29%) patients, and unilateral maxillary opacification was present in 12 of 23 (57%) patients. Dental pathology was not noted in 6 of 7 (86%) of pre-CT dental films and 14 of 21 (67%) of initial sinus CT reports but reevaluation of CT scans found dental pathology in all patients. CONCLUSION: Dental pathology causing sinusitis was frequently missed on plain dental X-rays and CT scan reports. Dental pain and foul-smelling nasal discharge are present in less than one-half of patients and symptoms commonly persist for years. Otolaryngologists must have a high index of suspicion for an odontogenic cause of refractory maxillary sinusitis.

Unrecognized odontogenic maxillary sinusitis: a cause of endoscopic sinus surgery failure.

BACKGROUND: Endoscopic sinus surgery (ESS) is reported to improve symptoms in approximately 85% of patients. Reasons for failure include misdiagnosis, technical inadequacies, underlying severe hyperplastic disease, biofilm, and immunodeficiency. Only one previous case of unrecognized odontogenic maxillary sinusitis has been cited in the literature as a reason for failure to improve with sinus surgery. This study was designed to characterize clinical and radiographic findings in patients who fail to improve with ESS because of an unrecognized dental etiology. METHODS: Five patients, with odontogenic maxillary sinusitis with prior unsuccessful ESS, were prospectively enrolled. Demographics and clinical aspects including duration of illness, prior sinus surgeries and therapies, and radiographic data were assessed. RESULTS: Five adults underwent an average of 2.8 sinus surgeries with persistence of disease and symptoms until their dental infection was treated. Duration of symptoms ranged from 3 to 15 years. In four of five patients, the periapical abscess was not noted on the original CT report but could be seen in retrospect. Three of five patients had been seen by their dentists and told they had no dental pathology. All five patients underwent dental extractions and one patient underwent an additional ESS after dental extraction. These procedures led to a resolution of sinusitis symptoms in all five patients. CONCLUSION: Unrecognized periapical abscess is a cause of ESS failure and the radiological report frequently will fail to note the periapical infection. Dentists are unable to recognize periapical abscesses reliably with dental x-rays and exam. In patients with maxillary sinus disease, the teeth should be specifically examined as part of the radiological workup.
