RESUMEN
Background: To explore the application of specialist nursing teams in patients undergoing unplanned interruptions in continuous renal replacement therapy. Methods: Sixty-six patients admitted to the intensive care unit of Jiangsu Province Hospital, China for continuous renal replacement therapy (CRRT) and experienced unplanned interruptions from Aug 2020 to Mar 2021 were enrolled as study subjects. Twenty four patients with conventional care were taken as the control group, and 42 patients in the specialized nursing team were taken as the experimental group. The age, type of disease, and degree of illness of the two groups were statistically processed and the differences were not significant (P>0.05) and were comparable. The control group received routine CRRT care after CRRT rescue, and the experimental group received CRRT care model from a specialized nursing team. Results: Patients in the group with specialized nursing care had 49 instances of CRRT unplanned interruptions, and the routine care group had 79 instances of CRRT unplanned interruptions. The number of unplanned interruptions in the experimental group was less than that of the control group, and the difference was statistically significant (P<0.001). The incidence of complications in the experimental group were lower than that of the control group (P<0.05). The satisfaction and quality of life of nurses in the specialist nursing group were clearly lower than those of the control group, and the difference was statistically significant (P<0.05). Conclusion: Specialist nursing teams could reduce the occurrence of unplanned interruptions in CRRT patients in intensive care and allow patients to receive continuity of care.
RESUMEN
In this research, we explored the effect of noise interruption rate on speech intelligibility. Specifically, we used the Hearing In Noise Test (HINT) procedure with the original HINT stimuli (English) and Igbo stimuli to assess speech reception ability in interrupted noise. For a given noise level, the HINT test provides an estimate of the signal-to-noise ratio (SNR) required for 50%-correct speech intelligibility. The SNR for 50%-correct intelligibility changes depending upon the interruption rate of the noise. This phenomenon (called Masking Release) has been studied extensively in English but not for Igbo - which is an African tonal language spoken predominantly in South Eastern Nigeria. This experiment explored and compared the phenomenon of Masking Release for (i) native English speakers listening to English, (ii) native Igbo speakers listening to English, and (iii) native Igbo speakers listening to Igbo. Since Igbo is a tonal language and English is a non-tonal language, this allowed us to compare Masking Release patterns on native speakers of tonal and non-tonal languages. Our results for native English speakers listening to English HINT show that the SNR and the masking release are orderly and consistent with other English HINT data for English speakers. Our result for Igbo speakers listening to English HINT sentences show that there is greater variability in results across the different Igbo listeners than across the English listeners. This result likely reflects different levels of ability in the English language across the Igbo listeners. The masking release values in dB are less than for English listeners. Our results for Igbo speakers listening to Igbo show that in general, the SNRs for Igbo sentences are lower than for English/English and Igbo/English. This means that the Igbo listeners could understand 50% of the Igbo sentences at SNRs less than those required for English sentences by either native or non-native listeners. This result can be explained by the fact that the perception of Igbo utterances by Igbo subjects may have been aided by the prediction of tonal and vowel harmony features existent in the Igbo language. In agreement with other studies, our results also show that in a noisy environment listeners are able to perceive their native language better than a second language. The ability of native language speakers to perceive their language better than a second language in a noisy environment may be attributed to the fact that: Native speakers are more familiar with the sounds of their language than second language speakers.One of the features of language is that it is predictable hence even in noise a native speaker may be able to predict a succeeding word that is scarcely audible. These contextual effects are facilitated by familiarity.
