The Impact

<b><i>Objective:</i></b> The purpose of this study was to evaluate the effects of nasal surgery on airflow characteristics in patients with obstructive sleep apnea (OSA) by comparing the alterations of airflow characteristics within the nasal and palatopharyngeal cavities. <b><i>Methods:</i></b> Thirty patients with OSA and nasal obstruction who underwent nasal surgery were enrolled. A pre- and postoperative 3-dimensional model was constructed, and alterations of airflow characteristics were assessed using the method of computational fluid dynamics. The other subjective and objective clinical indices were also assessed. <b><i>Results:</i></b> By comparison with the preoperative value, all postoperative subjective symptoms statistically improved (<i>p</i> &#x3c; 0.05), while the Apnea-Hypopnea Index (AHI) changed little (<i>p</i> = 0.492); the postoperative airflow velocity and pressure in both nasal and palatopharyngeal cavities, nasal and palatopharyngeal pressure differences, and total upper airway resistance statistically decreased (all <i>p</i> &#x3c; 0.01). A significant difference was derived for correlation between the alteration of simulation metrics with subjective improvements (<i>p</i> &#x3c; 0.05), except with the AHI (<i>p</i> &#x3e; 0.05). <b><i>Conclusion:</i></b> Nasal surgery can decrease the total resistance of the upper airway and increase the nasal airflow volume and subjective sleep quality in patients with OSA and nasal obstruction. The altered airflow characteristics might contribute to the postoperative reduction of pharyngeal collapse in a subset of OSA patients.

Objectives: Postoperative urinary retention (POUR) is influenced by many factors, and its reported incidence rate varies widely. This study aimed to investigate the occurrence and risk factors for urinary retention following general anesthesia for endoscopic nasal surgery in male patients aged >60 years. Methods: A retrospective review of medical records between January 2015 and December 2019 identified 253 patients for inclusion in our study. Age, body mass index (BMI), a history of diabetes/hypertension, American Society of Anesthesiologists (ASA) classification, and urologic history were included as patient-related factors. Urologic history was subdivided into 3 groups according to history of benign prostate hyperplasia (BPH)/lower urinary tract symptoms (LUTS) and current medication. The following was analyzed as perioperative variables for POUR development: duration of anesthesia and surgery; amount of fluid administered; rate of fluid administration; intraoperative requirement for fentanyl, ephedrine, and dexamethasone; postoperative pain; and analgesic use. Preoperatively measured prostate size and uroflowmetry parameters of patients on medication for symptoms were compared according to the incidence of urinary retention. Results: Thirty-seven (15.7%) patients developed POUR. Age (71.4 vs 69.6 years), BMI (23.9 vs 24.9 kg/m2), a history of diabetes/hypertension, ASA classification, and perioperative variables were not significantly different between patients with and without POUR. Only urologic history was identified as a factor affecting the occurrence of POUR ( P = .03). The incidence rate among patients without urologic issues was 5.9%, whereas that among patients with BPH/LUTS history was 19.8%. Among patients taking medication for symptoms, the maximal and average velocity of urine flow were significantly lower in patients with POUR. Conclusions: General anesthesia for endoscopic nasal surgery may be a potent trigger for urinary retention in male patients aged >60 years. The patient’s urological history and urinary conditions appear to affect the occurrence of POUR.

Abstract Background Preventing emergence cough after nasal surgery is critical. Emergence cough can provoke immediate postoperative bleeding, which leads to upper airway obstruction. In the present study, we compared the effect-site concentration (Ce) of remifentanil to prevent emergence cough after propofol anesthesia for nasal surgery when remifentanil was or was not combined with dexmedetomidine. Methods Forty-seven patients with propofol-remifentanil anesthesia for nasal surgery were randomly assigned to a dexmedetomidine group (Group D, n = 23) or a saline group (Group S, n = 24). Group D and Group S were infused with dexmedetomidine (0.5 μg/kg) and saline, respectively, for 10 min before the completion of surgery. A predetermined Ce of remifentanil was infused until extubation. Remifentanil Ce to prevent cough in 50 and 95% of patients (EC50 and EC95) was estimated using modified Dixon’s up-and-down method and isotonic regression. Hemodynamic and recovery parameters were recorded. Results The EC50 of remifentanil Ce was significantly lower in Group D than in Group S (2.15 ± 0.40 ng/mL vs. 2.66 ± 0.36 ng/mL, p = 0.023). The EC95 (95% CI) of remifentanil Ce was also significantly lower in Group D [2.75 (2.67–2.78) ng/mL] than in Group S [3.16 (3.06–3.18) ng/mL]. Emergence and recovery variables did not differ between the two groups. Conclusion The remifentanil EC50 to prevent cough after propofol-remifentanil anesthesia was significantly lower (approximately 19%) when a combination of remifentanil and 0.5 μg/kg dexmedetomidine was used than when remifentanil infusion alone was used in patients undergoing nasal surgery. Therefore, the Ce of remifentanil may be adjusted to prevent emergence cough when used in combination with dexmedetomidine. Trial registration ClinicalTrials.gov (NCT03622502, August 9, 2018).
