“…Since then, HFJV has become a technique to maintain ventilation. The application of this technique enables rapid pulsation gas to enter the respiratory tract through a narrow jet tube under low pressure [25, 26]. HFJV has three characteristics [27–29], open system, high-frequency (> 60 bpm) and low tidal volume.…”

Background Supraglottic jet oxygenation and ventilation (SJOV) can effectively maintain adequate oxygenation in patients with respiratory depression, even in apnea patients. However, there have been no randomized controlled clinical trials of SJOV in obese patients. This study investigated the efficacy and safety of SJOV using WEI Nasal Jet tube (WNJ) for obese patients who underwent hysteroscopy under intravenous anesthesia without endotracheal intubation. Methods A single-center, prospective, randomized controlled study was conducted. The obese patients receiving hysteroscopy under intravenous anesthesia were randomly divided into three groups: Control group maintaining oxygen supply via face masks (100% oxygen, flow at 6 L/min), the WNJ Oxygen Group with WNJ (100% oxygen, flow: 6 L/min) and the WNJ SJOV Group with SJOV via WNJ [Jet ventilator working parameters:100% oxygen supply, driving pressure (DP) 0.1 MPa, respiratory rate; (RR): 15 bpm, I/E; ratio 1:1.5]. SpO 2 , P ET CO 2 , BP, HR, ECG and BIS were continuously monitored during anesthesia. Two-Diameter Method was deployed to measure cross sectional area of the gastric antrum (CSA-GA) by ultrasound before and after SJOV in the WNJ SJOV Group. Episodes of SpO 2 less than 95%, P ET CO 2 less than 10 mmHg, depth of WNJ placement and measured CSA-GA before and after jet ventilation in the WNJ SJOV Group during the operation were recorded. The other adverse events were collected as well. Results A total of 102 patients were enrolled, with two patients excluded. Demographic characteristics were similar among the three groups. Compared with the Control Group, the incidence of P ET CO 2 < 10 mmHg, SpO 2 < 95% in the WNJ SJOV group dropped from 36 to 9% ( P = 0.009),from 33 to 6% ( P = 0.006) respectively,and the application rate of jaw-lift decreased from 33 to 3% ( P = 0.001), and the total percentage of adverse events decreased from 36 to 12% ( P = 0.004). Compared with the WNJ Oxygen Group, the use of SJOV via WNJ significantly decreased episodes of SpO 2 < 95% from 27 to 6% ( P = 0.023), P ET CO 2 < 10 mmHg from 33 to 9% ( P = 0.017), respectively. Depth of WNJ placement was about 12.34 cm in WNJ SJOV Group. There was no significantly difference of CSA-GA before and after SJOV in the WNJ SJOV Group ( P = 0.234). There were no obvious cases of nasal bleeding in all the three groups. Conclusions SJOV can effectively and safely maintain adequate oxygenati...

Objective: This study is conducted to evaluate the efficacy and safety of using multifunctional intubation laryngeal masks with normal frequency jet ventilation in airway interventional therapy. Methods: A total of 200 patients receiving airway interventional therapy were enrolled in this retrospective study and were divided into 2 groups (group M and group P) by doctors in our hospital to compare the effect of different laryngeal masks. Group M used common laryngeal masks and an anesthesia machine for positive pressure ventilation while group P took multifunctional intubation laryngeal masks and used a jet ventilator for normal frequency jet ventilation. The patients’ mean arterial pressure, heart rate, arterial oxygen partial pressure (PaO2) and arterial carbon dioxide partial pressure (PaCO2), and the operation time, recovery score and the patients’ and doctors’ satisfaction levels were compared between the 2 groups. Results: Both groups were hemodynamically stable, and their PaO2 levels were significantly higher before the operation than that during and after the operation (P < .05). Compared with group M, the PaCO2 level of group P was more stable both during and after the operation, and this difference was statistically significant (P < .05). There was no statistically significant difference in terms of the 2 group’s operating time, recovery score, and patients’ satisfaction levels (P > .05). However, the satisfaction levels of doctors in group P were higher than that in group M, and this difference was statistically significant (P < .05). Conclusion: As statistics show, the intraoperative hemodynamics and PaO2 and PaCO2 levels were stable, and patients, surgeons and anesthesia operators were satisfied. Therefore, it is feasible to apply multifunctional intubation laryngeal masks with normal frequency jet ventilation in airway interventional therapy and it is a safe and ideal way to ensure ventilation.

“…IAH links to elevated SOFA scores, high APACHE II, high APACHE III, a further need for mechanical ventilation and insufficient PaO2: FiO2 ratios at admission time. Longer durations of the need for mechanical ventilation and lengths of stay at ICUs in such patients reaffirm the pathophysiological damages of raised ICP [19].…”

BACKGROUND: Abdominal compartment syndrome patients suffer severe obstacles such as kidney failure and shock. To evade further complications, identifying the abdominal compartment syndrome (ACS) and Intra-abdominal hypertension (IAH), in critically ill individuals and hospitalised in the intensive care unit (ICU) is obligated. AIM: The current study intended to study the abdominal compartment syndrome and the concomitant risk factors among hospitalised patients in ICU, by using the Intra-abdominal pressure test. MATERIAL AND METHODS: One hundred and twenty-five hospitalised patients at ICU entered the current survey. Abdominal pressure was measured by standard intravesical technique. The SPSS 21 analysed the preoperative and intraoperative factors such as demographic records and comorbidities. RESULTS: Seventy-three (58.4%) participants were males, and 52 (41.6%) were women in the mean age of 55.1 ± 18.3 years. Eighty-nine patients (71.2%) showed normal intra-abdominal pressure since 31 patients (24.8%), and 5 patients (4%) developed IAH and ACS. The intra-abdominal pressure (IAP) applied to Glasgow Coma Scale (GCS), Acute Physiology, shock, Systemic Inflammatory Response Syndrome (SIRS), central venous oxygen saturation and Chronic Health Evaluation (APACHE II) score (P < 0.05). Patients with high IAP have shown a higher mortality frequency, compared to others (P < 0.05). CONCLUSION: Current findings showed a correlation between IAP hospitalised patients in ICU and shock, SIRS, APACHE II, central venous oxygen saturation and GCS. Intra-abdominal pressure test, as a valuable prognosis test for the abdominal compartment syndrome (ACS) and Intra-abdominal hypertension (IAH), may offer better results when added to the routine medical checkup of ICU patients.
