Transoral robotic-assisted tongue base resection in pediatric obstructive sleep apnea syndrome: case presentation, clinical and technical consideration.

Pediatric obstructive sleep apnea syndrome (OSAS) is primarily caused by adenotonsillar hypertrophy. However, tongue base hypertrophy is increasingly being recognized as a cause, even after adenotonsillectomy. We report three cases of pediatric OSAS successfully treated by transoral robotic reduction of the tongue base. In all children, we were able to achieve improved retrolingual patency while avoiding significant procedure-related morbidity. In conclusion, tongue base reduction by transoral robotic surgery appears to be a feasible solution for the base of tongue obstruction due to lingual tonsil hypertrophy in pediatric patients.

Operating room data management: improving efficiency and safety in a surgical block.

BACKGROUND: European Healthcare Systems are facing a difficult period characterized by increasing costs and spending cuts due to economic problems. There is the urgent need for new tools which sustain Hospitals decision makers work. This project aimed to develop a data recording system of the surgical process of every patient within the operating theatre. The primary goal was to create a practical and easy data processing tool to give hospital managers, anesthesiologists and surgeons the information basis to increase operating theaters efficiency and patient safety. METHODS: The developed data analysis tool is embedded in an Oracle Business Intelligence Environment, which processes data to simple and understandable performance tachometers and tables. The underlying data analysis is based on scientific literature and the projects teams experience with tracked data. The system login is layered and different users have access to different data outputs depending on their professional needs. The system is divided in the tree profile types Manager, Anesthesiologist and Surgeon. Every profile includes subcategories where operators can access more detailed data analyses. The first data output screen shows general information and guides the user towards more detailed data analysis. The data recording system enabled the registration of 14.675 surgical operations performed from 2009 to 2011. RESULTS: Raw utilization increased from 44% in 2009 to 52% in 2011. The number of high complexity surgical procedures (≥120 minutes) has increased in certain units while decreased in others. The number of unscheduled procedures performed has been reduced (from 25% in 2009 to 14% in 2011) while maintaining the same percentage of surgical procedures. The number of overtime events decreased in 2010 (23%) and in 2011 (21%) compared to 2009 (28%) and the delays expressed in minutes are almost the same (mean 78 min). The direct link found between the complexity of surgical procedures, the number of unscheduled procedures and overtime show a positive impact of the project on OR management. Despite a consistency in the complexity of procedures (19% in 2009 and 21% in 2011), surgical groups have been successful in reducing the number of unscheduled procedures (from 25% in 2009 to 14% in 2011) and overtime (from 28% in 2009 to 21% in 2011). CONCLUSIONS: The developed project gives healthcare managers, anesthesiologists and surgeons useful information to increase surgical theaters efficiency and patient safety. In difficult economic times is possible to develop something that is of some value to the patient and healthcare system too.

Perioperative management and surgical field optimization in functional endoscopic sinus surgery.

A sound anesthesiologist-surgeon collaboration is crucial for the success of functional endoscopic sinus surgery (FESS). The aim of this narrative review was to describe if and how anesthetic choice can decrease bleeding and improve visibility in the surgical field (VSF) and thus contribute to successful FESS. A literature search was conducted on evidence-based practices published from 2011 to 2021 describing perioperative care, intravenous/inhalation anesthetics, and operative approaches for FESS and their effects on blood loss and VSF. With regards to preoperative care and operative approaches, best clinical practices include topical vasoconstrictors at the time of surgery, medical management (steroids) preoperatively, and patient positioning, as well as anesthetic techniques including controlled hypotension, ventilation settings, and anesthetics choices. Four out of five meta-analyses and six out of 11 randomized controlled trials favored total intravenous anesthesia (TIVA) over inhalation anesthesia (IA) for improved VSF. The effects on VSF were more dependent on adjunct medications used (remifentanil, alpha-2 agonists, etc.), rather than the choice of anesthetic technique (i.e., TIVA vs. IA). The current literature is inconclusive regarding the impact of anesthetic choice on VSF during FESS. We recommend that anesthesiologists use the anesthetic technique with which they are most comfortable to facilitate efficiency, recovery, cost, and collaboration with the perioperative team. Future studies should be designed to consider disease severity, the method for measuring blood loss, and a standardized VSF score. Studies should also investigate the long-term effects of TIVA- and IA- induced hypotension.

Blind intubation through Laryngeal Mask Airway in a cannot intubate-difficult to ventilate patient with massive hematemesis.

Massive hematemesis could be challenging situation requiring emergency airway control and urgent surgical treatment. We report a case of difficult airway management with blind intubation through Laryngeal Mask Airway in a 56-year-old patient with massive hematemesis. After failed endoscopic attempts to stop bleeding, worsening of hemodynamics called for emergency intubation and surgery. After failed intubation attempts and face-mask ventilation worsening, a classic LMA was used for rescue ventilation and decision was made to intubate through LMA. The airway exchange was aided by a nasogastric tube (NGT) through LMA, confirmed with capnography and surgery was started successfully and uneventfully. Unexpected difficult airway can be extremely challenging situation, especially in emergency settings with no possibility to delay surgery. In those cases, literature suggests different intubating techniques through LMA. Blind intubation through LMA aided by NGT showed to be a suitable option in resources-limited settings, where advanced supraglottic devices and/or optical devices are not available.

Ultrasound-guided erector spinae block for post-thoracotomy pain syndrome in video-assisted thoracic surgery.

This article describes our experience with 5 patients with post-thoracotomy pain syndrome after video-assisted thoracoscopic lobectomies, treated with weekly erector spinae plane block. We injected corticosteroid and local anesthetic. At the end of the treatment period, pain scores decreased significantly. Our experience suggests that erector spinae plane block may have a role in the treatment of post-thoracoscopy pain syndrome.

Safety and efficacy of Staged Extubation Set in patients with difficult airway: a prospective multicenter study.

BACKGROUND: A safe extubation is the extension of any airway management strategy. Despite different guidelines, a number of extubation accidents still occurs. Re-intubation failure could be fatal, thus a strategy and safe and efficient devices for this purpose are essential. METHODS: Multicentric prospective observational study on adult patients with endotracheal intubation and known difficult airway. A Staged Extubation Set® (SES) was used for extubation. Demographics, ASA, El Ganzouri, type of surgery, re-intubation success/failure and complications were recorded. The aim of the study was the assessment of the rate of re intubation failure, complications during failures, patients' comfort and evidence of airway injury. RESULTS: Overall, 114 subsequent difficult airway patients were enrolled. Fifteen patients (13%) required re-intubation: ten of 15 (66%) were successfully re-intubated, with a first-pass success rate of 100%. In five patients (33%), re-intubation over SES was unsuccessful, with re-intubation difficulty rate three (easy), three (quite easy) and nine (very difficult) and five cases of desaturation. Complications included one case of esophageal intubation, one case of lip trauma, and two cases of airway edema. Of 114 patients, eight (7%) perceived the procedure as intolerable. CONCLUSIONS: The results from this study show a relatively satisfactory success rate with a relatively high number of re-intubations failure and a low incidence of complications when using a SES in a cohort of difficult airway patients, all failures due to guidewire dislodgement during or after extubation. Further research is needed to improve success rate; at the same time the need for an extubation protocol is strongly advocated.

Perioperative Care of Patients With Obstructive Sleep Apnea Undergoing Upper Airway Surgery: A Review and Consensus Recommendations.

IMPORTANCE: To date, no consensus exists regarding optimal perioperative care of patients with obstructive sleep apnea (OSA) undergoing upper airway (UA) surgery. These patients are at risk related to anesthesia and postoperative analgesia, among other risks associated with difficult airway control, and may require intensified perioperative management. OBJECTIVE: To provide a consensus-based guideline by reviewing available literature and collecting expert opinion during an international consensus meeting with experts from relevant speciliaties. EVIDENCE REVIEW: In a consensus meeting conducted on April 4, 2018, a total of 47 questions covering preoperative, intraoperative, and postoperative care were formulated by 12 international experts with extensive clinical experience in the field of UA surgery for OSA. Systematic literature searches were performed by an independent information specialist and 6 researchers according to the Oxford and GRADE systems, and 164 articles published on or before December 31, 2011, were included in the analysis. Two moderators chaired the meeting according to the Amsterdam Delphi Method, including iteration of literature conclusions, expert discussion, and voting rounds. Consensus was reached when there was 70% or more agreement among experts. FINDINGS: Of 47 questions, 35 led to a recommendation or statement. The remaining 12 questions provided no additional information and were excluded in the judgment of experts. Consensus was reached for 32 recommendations. For 1 question there was less than 70% agreement among experts; therefore, consensus was not achieved. Highlights of these recommendations include (1) postoperative bleeding is a complication described for all types of UA surgery; (2) OSA is a relative risk factor for difficult mask ventilation and intubation, and plans for difficult airway management should be considered and implemented; (3) safe perioperative care should be provided, with aspects such as OSA severity, adherent use of positive airway pressure, type of surgery, and comorbidities taken into account; (4) although there is no direct evidence to date, in patients undergoing UA surgery, preoperative treatment with positive airway pressure may reduce the risk of postoperative airway complications; and (5) alternative pain management options perioperatively to reduce opioid use should be considered. CONCLUSIONS AND RELEVANCE: This consensus contains 35 recommendations and statements on the perioperative care of patients with OSA undergoing UA surgery and may be used as a guideline in daily practice.

[Post analysis simulated correlation of the El-Ganzouri airway difficulty score with difficult airway]. / Correlação simulada após análise dos escores de El-Ganzouri para via aérea difícil.

BACKGROUND: Difficult airway (DA) occurs frequently (5-15%) in clinical practice. The El-Ganzouri Risk Index (EGRI) has a high sensitivity for predicting a difficult intubation (DI). However difficult mask ventilation (DMV) was never included in the EGRI. Since DMV was not included in the EGRI assessment, and obstructive sleep apnea (OSA) is also correlated with DMV, a study correlating the prediction of DA and OSA (identified by STOP-Bang questionnaire, SB) seemed important. METHODS: We accessed a database previously collected for a post analysis simulation of the airway difficulty predictivity of the EGRI, associated with normal and difficult airway, particularly DMV. As secondary aim, we measured the correlation between the SB prediction system and DA, compared to the EGRI. RESULTS: A total of 2747 patients were included in the study. The proportion of patients with DI was 14.7% (95% CI 13.4-16) and the proportion of patients with DMV was 3.42% (95% CI 2.7-4.1). The incidence of DMV combined with DI was (2.3%). The optimal cutoff value of EGRI was 3. EGRI registered also an higher ability to predict DMV (AUC=0.76 (95% CI 0.71-0.81)). Adding the SB variables in the logistic model, the AUC increases with the inclusion of "observed apnea" variable (0.83 vs. 0.81, p=0.03). The area under the ROC curve for the patients with DI and DMV was 0.77 (95% CI 0.72-0.83). CONCLUSIONS: This study confirms that the incidence of DA is not negligible and suggests the use of the EGRI as simple bedside predictive score to improve patient safety.
