Application Effect Evaluation of Optimizing Emergency Nursing Process Before Emergency Coronary Intervention in Patients with AMI and Hypertension.

Objective: The study aimed to assess the impact of optimizing the emergency nursing process on certain outcomes in AMI patients with hypertension undergoing coronary intervention therapy. Methods: This is a retrospective cohort study, a total of 90 patients with AMI complicated with hypertension admitted from October 2020 to March 2022 to observe the effect and safety of two different nursing methods in patients with AMI complicated with hypertension. According to the different nursing process, the subjects were divided into the optimization and conventional groups, with 45 cases in each group. Then, the rescue efficiency, success rate, recurrence rate, re-PCI rate, negative emotions, and adverse reactions of the two groups were observed. Results: The results showed that the first aid time (39.23±6.28 vs 49.78±9.14), PCI time (45.13±8.60 vs 60.40±8.16) and ECG time (4.18±0.69 vs 6.87±1.00), success rate (93.33% vs 66.67%) and recurrence rate (8.89% vs 22.22%) of the study subjects undergoing the optimized emergency nursing process were significantly better than those undergoing the general emergency nursing process (P < .05), and their negative emotions (7.51±1.77 vs 14.07±1.93) and adverse reactions (3 vs 9) were significantly lower than those of the conventional group (P < .05). Conclusions: It is suggested that optimizing the emergency nursing process before PCI for patients with AMI complicated with hypertension positively impacts the clinical efficacy and prognosis. Optimizing the emergency nursing process may potential benefits for patient health, healthcare resource utilization, or the quality of care, which should be consider in clinical practice.

The effects of high-intensity, low-frequency active sonar on rainbow trout.

This study investigated the effects on rainbow trout (Oncorhynchus mykiss) of exposure to high-intensity, low-frequency sonar using an element of the standard Surveillance Towed Array Sensor System Low Frequency Active (LFA) sonar source array. Effects of the LFA sonar on hearing were tested using auditory brainstem responses. Effects were also examined on inner ear morphology using scanning electron microscopy and on nonauditory tissues using general pathology and histopathology. Animals were exposed to a maximum received rms sound pressure level of 193 dB re 1 microPa(2) for 324 or 648 s, an exposure that is far in excess of any exposure a fish would normally encounter in the wild. The most significant effect was a 20-dB auditory threshold shift at 400 Hz. However, the results varied with different groups of trout, suggesting developmental and/or genetic impacts on how sound exposure affects hearing. There was no fish mortality during or after exposure. Sensory tissue of the inner ears did not show morphological damage even several days post-sound exposure. Similarly, gross- and histopathology observations demonstrated no effects on nonauditory tissues.
