A Framework for Prioritizing Head and Neck Surgery during the COVID-19 Pandemic.
Head & neck
The COVID-19 pandemic has placed an extraordinary demand on the United States healthcare system. Many institutions have cancelled elective and non-urgent procedures to conserve resources and limit exposure. While operational definitions of elective and urgent categories exist, there is a degree of surgeon judgment in designation. In the present commentary, we provide a framework for prioritizing head and neck surgery during the pandemic. Unique considerations for the head and neck patient are examined including risk to the oncology patient, outcomes following delay in head and neck cancer therapy, and risk of transmission during otolaryngologic surgery. Our case prioritization criteria consist of four categories: urgent - proceed with surgery, less urgent - consider postpone >30 days, less urgent - consider postpone 30-90 days, and case-by-case basis. Finally, we discuss our preoperative clinical pathway for transmission mitigation including defining low-risk and high-risk surgery for transmission and role of preoperative COVID-19 testing.

Overlapping Surgery: A Case Study in Operating Room Throughput and Efficiency.
2018; 36 (2): 161–76
A keystone of operating room (OR) management is proper OR allocation to optimize access, safety, efficiency, and throughput. Access is important to surgeons, and overlapping surgery may increase patient access to surgeons with specialized skill sets and facilitate the training of medical students, residents, and fellows. Overlapping surgery is commonly performed in academic medical centers, although recent public scrutiny has raised debate about its safety, necessitating monitoring. This article introduces a system to monitor overlapping surgery, providing a surgeon-specific Key Performance Indicator, and discusses overlapping surgery as an approach toward OR management goals of efficiency and throughput.

Dexmedetomidine and ketamine for fiberoptic intubation in a child with severe mandibular hypoplasia
JOURNAL OF CLINICAL ANESTHESIA
2008; 20 (6): 455-457
A 6-year-old girl with Treacher Collins syndrome presented for implantation of a hearing device. The patient was developmentally delayed and had severe micrognathia. After induction of anesthesia with dexmedetomidine and ketamine, the patient tolerated the introduction of a flexible fiberoptic bronchoscope without any change in respiration, and intubation was achieved easily.

Successful blood conservation during craniosynostotic correction with dual therapy using procrit and cell saver
JOURNAL OF CRANIOFACIAL SURGERY
2008; 19 (1): 101-105
Craniosynostotic correction typically performed around infant physiologic nadir of hemoglobin (approximately 3-6 months of age) is associated with high transfusion rates of packed red blood cells and other blood products. As a blood conserving strategy, we studied the use of 1) recombinant human erythropoietin or Procrit (to optimize preoperative hematocrit) and 2) Cell Saver (to recycle the slow, constant ooze of blood during the prolonged case).UCLA Patients with craniosynostosis from 2003-2005 were divided into 1) the study group (Procrit and Cell Saver) or 2) the control group (n = 79). The study group 1) received recombinant human erythropoietin at 3 weeks, 2 weeks, and 1 week preoperatively and 2) used Cell Saver intraoperatively. Outcomes were based on morbidities and transfusion rate comparisons.The 2 groups were comparable with regards to age (5.66 and 5.71 months), and operative times (3.11 vs 2.59 hours). In the study group there was a marked increase in preoperative hematocrit (56.2%). The study group had significantly lower transfusions rates (5% vs 100% control group) and lower volumes transfused than in the control group (0.05 pediatric units vs 1.74 pediatric units). Additionally, of the 80% of patients in the study group who received Cell Saver blood at the end of the case, approximately 31% would have needed a transfusion if the recycled blood were unavailable.Our data showed that for elective craniosynostotic correction, successful blood conserving dual therapy with Procrit and Cell Saver might be used to decrease transfusion rates and the need for any blood products.

Continuous monitoring of dynamic pulmonary compliance enables detection of endobronchial intubation in infants and children
ANESTHESIA AND ANALGESIA
2007; 105 (1): 51-56
Auscultation of breath sounds is used routinely to confirm tracheal placement of endotracheal tubes (ETT). In infants and children, this method is limited by the conduction of breath sounds bilaterally, despite endobronchial intubation. Although several methods of detecting endobronchial intubation have been described, none is both simple and reliable. In this investigation, we determined whether changes in pulmonary compliance and airway pressures, measured using continuous side stream spirometry, can reliably detect endobronchial intubation in pediatric patients.Forty patients aged 1 month to 6 years were included. After endotracheal intubation the ETT was incrementally advanced as two observers monitored breath sounds and spirometry (Pressure-Volume Loops). Changes in pulmonary compliance, peak inspiratory pressure, or auscultation were reported, at which point ETT position was confirmed by fiberoptic bronchoscopy.Endobronchial intubation decreased measured pulmonary compliance by 45 +/- 11% (mean +/- sd; P < 0.001, Range 26%-66%) and increased peak airway pressures by 26 +/- 17% (mean +/- sd; P < 0.001, Range 0-87). Changes in peak airway pressures were smaller and more variable when compared to changes in compliance. Breath-sound auscultation failed to detect endobronchial intubation in 7.5% of cases.Pulmonary compliance changes are a sensitive and an accurate indicator of endobronchial intubation in infants and children. Both increased peak airway pressures and changes in breath sounds are less sensitive indicators of endobronchial intubation.

Experience with the Arndt paediatric bronchial blocker
BRITISH JOURNAL OF ANAESTHESIA
2005; 94 (1): 92-94
Previously reported techniques for single lung ventilation in children have failed to provide consistent, single lung ventilation with relative ease and reliability. We report our experience with the use of a new device, the Arndt 5 French (Fr) paediatric endobronchial blocker, for single lung ventilation in a series of 24 children. We were able to achieve single lung ventilation in 23 of the 24 patients (aged 2-16 yr). Placement required approximately 5-15 min. Attempts at placement were aborted in one patient who was unable to tolerate even short periods of apnoea because of lung pathology. Although it has some limitations, our experience suggests that the paediatric bronchial blocker can be used as a consistent, safe method of single lung ventilation in most young children.
