OBJECTIVE: To compare the effectiveness of vocal cord cyst excision with electronic laryngoscope (EL) and self-retaining laryngoscope (SRM). METHOD: Nightly-two patients, diagnosed as vocal cord cyst with strobolaryngoscope or electronic laryngoscope, were randomly divided into two groups. One group was 48 cases treated with electronic laryngoscope and another group was 44 cases treated with self-retaining laryngoscope. Electronic laryngoscopy examination and voice function assessments were performed to all patients, preoperatively and postoperatively at one week, three months and six months. RESULT: One failed cases under SRM, difficult exposure of glottic portion, were treated under EL. The recurrence rate of the two groups was of no statistical significance in three months after operation. Voice function assessment of the two groups was of no statistical significance at one week, three months and six months after operation. CONCLUSION The operation under electronic laryngoscope is a minimal invasive procedure to the laryngeal mucosa. Electronic laryngoscope had advantages such as clear view, accurate operation. Furthermore, it can be used for those that could not be treated under self-retaining laryngoscope.

OBJECTIVETo explore the value of color doppler ultrasound examination of thyroid in occupational health care of radiation-exposed physicians.

METHODSOne hundred and thirty-four radiation-exposed physicians (observation group) and sixty-eight non-radiation-exposed physicians (control group) received color doppler ultrasound examination of thyroid using ALOKA SSD-4000 color doppler ultrasonic diagnostic apparatus, and the results were compared between the two groups.

RESULTSThe anteroposterior diameters of the left lobe, right lobe, and isthmus of the thyroid in the observation group were significantly larger than those in the control group (P < 0.01). Compared with the control group, the observation group had significantly larger internal diameters and peak blood flow velocities during systole of the right superior thyroid artery (P < 0.05, P < 0.05). There were no significant differences in detection rates of thyroid nodules and lymph nodes between the observation group and the control group (18.7% vs 13.2%, P > 0.05; 6.7% vs 1.5%, P > 0.05). The radiation-exposed physicians were exposed to low-dose ionizing radiation with a dose between 0.14 and 1.67 mSv/a.

CONCLUSIONThe color doppler ultrasound examination of the thyroid can detect early changes in the thyroid of radiation-exposed physicians exposed to long-term and low-dose ionizing radiation.

Objective:To explore the observation and nursing of patients with acute mass asphyxia poisoning with pulmonary bullae treated by nasal high-flow humidification and oxygen therapy.Methods:Review and summarize the data of 5 patients with acute mass asphyxial gas poisoning with pulmonary vesicles who were admitted to the department of toxicology of this hospital in June 2019 and received nasal high-flow humidification and oxygen therapy. The oxygenation index, airway humidification and prognosis were observed.Results:All the 5 patients were successfully transferred to nasal catheter for oxygen inhalation after nasal high-flow humidification and orygen therapy without intubation. When discharged from the hospital without oxygen, pH: 7.36-7.42, PO 2:82-106 mmHg, PCO 2:32-39 mmHg. All the white blood cells and myocardial enzymes were normal, and there was no brain injury, perinasal skin damage and abdominal distension. Conclusion:Nasal high-flow humidification and oxygen therapy can effectively improve the efficacy of oxygen therapy for patients with acute mass asphyxial gas poisoning with pulmonary vacuoles.
