“…THRIVE uses a relatively constant concentration, temperature, and humidity at a high flow rate of up to 70 L/min via the nasal cannula. Studies have shown that THRIVE can extend the asphyxia window for patients under general anesthesia to 65 min for patients with difficult airway management [ 13 ]. Hua and colleagues found that THRIVE significantly extended the SAT in elderly patients after rapid sequence induction of anesthesia compared to facemask [ 5 ], which is consistent with our results.…”

“…Possible reasons are as follows: (1) THRIVE uses a nasal catheter to administer high-concentration and high-flow oxygen and is unaffected by tooth loss. (2) THRIVE facilitates oxygenation by delivering high-flow pure oxygen with a maximum velocity of 70 L/min and a small amount of CPAP, which opens the upper respiratory tract and even the distal airway, decreasing ventilatory dead space and reducing the likelihood of atelectasis [ 13 ]. (3) The facemask usually needs to be removed during endotracheal intubation, which leads to an interruption of oxygenation.…”

Background Edentulous elderly patients often face challenges in airway management and are susceptible to hypoxemia. Transnasal humidified rapid-insufflation ventilatory exchange (THRIVE) provides high-flow nasal oxygenation, potentially extending safe apneic time (SAT). This study compared the efficacy of THRIVE versus facemask ventilation in improving oxygenation and extending SAT in edentulous elderly patients. Material/Methods Patients with more than 10 missing teeth and who were over 65 years old were randomly assigned to the facemask group (Group M, n =25) or the THRIVE group (Group T, n =25). Patients in Group M were pre-oxygenated with a facemask (6 L/min, FiO 2 100%), while patients in Group T were pre-oxygenated with their mouths closed via THRIVE (30 L/min, FiO 2 100%). After anesthesia induction, patients in Group M were ventilated with pressure-controlled ventilation. In Group T, the patient’s mouth was kept closed, and the flow rate was adjusted to 70 L/min. Four min after cisatracurium administration, ventilation was stopped in Group M while Group T continued to receive oxygen (70 L/min, FiO 2 100%). The primary outcome was SAT, which was attained at 4 min after injection of cisatracurium and ended when SpO 2 decreased to 95% or when apneic time reached 480 s. A secondary outcome was the reoxygenation time, defined as the time from the beginning of mechanical ventilation to the time when SpO 2 98% was reached. Results An SAT of 480 s was reached by all patients in Group T, but by only 6 patients in Group M ( P <0.05). Compared with Group M, the reoxygenation time in Group T was significantly shorter ( P <0.05). Conclusions As compared to facemask, THRIVE can extend the SAT, improve oxygenation, and reduce reoxygenation time.

“…THRIVE also provides a small amount of continuous positive airway pressure (CPAP), potentially opening the upper respiratory airway and even the distal alveoli and so reducing ventilatory dead space. This may help reduce the occurrence of atelectasis and increase alveolar ventilation [13]. This mechanism may contribute to the prolongation of the safe apneic duratioshorten the reoxygenation time.…”

Objective: To compare the effect of THRIVE with face mask ventilation on oxygenation and safe apneic duration after induction of general anesthesia in elderly minimally-toothed patients. Method:Single university-affiliated hospital, conducted from October 2021 to December 2021. Totally 50 patients aged ≥ 65 years with ≥ 10 missing teeth, American Society of Anesthesiology physical status I-III, Mallampati class I-II, who underwent elective surgery under general anesthesia with tracheal intubation, were randomly enrolled and assigned to a facemask group (Group M) and a THRIVE group (Group T) with a random number table. Patients in Group M were pre-oxygenated with a facemask (100% oxygen at a flow rate of 6 L/min). In Group T, patients with their mouths closed were pre-oxygenated via THRIVE (100% oxygen at a flow rate of 30 L/min). After anesthesia induction, patients in Group M were ventilated with pressure-controlled ventilation, and then the facemask was removed to stop the mask ventilation. In Group T, the patient’s mouth was kept closed, and the flow rate was adjusted to 70 L/min. Then, THRIVE was continued with an open mouth. When the safe apneic duration lasted up to 8 minutes or SpO2 decreased to 95%, observation was ended, and the patient was immediately intubated with a video laryngoscope. Tracheal intubation was successfully performed on the first attempt. The safe apneic time (SAT) (from 4 min after muscle relaxant administration to the time until SpO2 dropped to 95%) was measured. Result: Fifty patients were included in the trail. Group T patients had a significantly longer SAT compared to Group M (P=0.000). All 25 patients in Group T reached 8 minutes with their SpO2 maintained at >95%. In Group M, 6 patients (24%) maintained their SpO2 at >95% for 8 minutes. Conclusion: THRIVE, compared with facemask ventilation, can significantly increase the safe apneic duration, improve oxygenation, and shorten the reoxygenation time in elderly minimally-toothed patients during the induction of general anesthesia, which contributes to stable hemodynamics and safe tracheal intubation.
