Cochlear implantation is the most effective method to restore hearing in patients with severe and profound hearing impairment.There are individual differences in rehabilitation after cochlear implantation.In order to better understand the underlying factors of rehabilitation,machine learning has been gradually applied to the reha-bilitation prediction of cochlear implant patients.Since related literature is still in its infancy,many problems still remain unresolved,such as insufficient sample size and lack of diversification of data features.We suggest that fu-ture research may expand the sample size,optimize machine learning models,and fully explore the predictive factors affecting the rehabilitation of cochlear implantation,and make machine learning a better tool in the area of cochlear implantation.

Objective To compare the anesthetic effect and safety of Ciprofol and Propofol combined with Fentanyl in painless bronchoscopy for conscious patients in intensive care unit(ICU).Methods 60 conscious patients who underwent painless bronchoscopy from October 2022 to January 2023 were selected.According to the random number table method,30 cases were divided into the control group(Propofol 1.5 mg/kg + Fentanyl 1 μg/kg)and 30 cases were divided into the experimental group(Ciprofol 0.4 mg/kg + Fentanyl 1 μg/kg).Systolic blood pressure,diastolic blood pressure,heart rate,respiratory frequency,and percutaneous arterial oxygen saturation(SpO2)were recorded before anesthesia(T1),during the examination(T2),and at the completion of the examination(T3)in the two groups,and the success rate of induction of general anesthesia,the time of induction of anesthesia,the time of bronchoscopy,the time of eye-opening,the total dosage of medications used,the incidence of injection pain,and the incidence of intraoperative adverse reactions(hypotension,respiratory depression,bradycardia,and bucking)in the two groups were compared.Results Analysis of the data revealed significant group,time,and interaction effects for systolic blood pressure,diastolic blood pressure,heart rate,and respiratory frequency at different time points(P<0.05).The experimental group had a shorter induction time of anesthesia[1.40(1.10,1.62)min]in comparison to the control group[1.60(1.30,2.10)min](P<0.05),and the experimental group required a less amount of drug to achieve the desired outcome[(21.40±1.82)mg]compared to the control group[(78.75±6.71)mg](P<0.05).Furthermore,the incidence of injection pain(3.33%)and respiratory depression(6.67%)was significantly reduced in the experimental group compared to the control group(36.67%)and(30.00%)(P<0.05).Conclusion The use of Ciprofol in combination with Fentanyl has been found to provide effective anesthesia during bronchoscopy,while also increasing safety and decreasing the incidence of adverse events.It is worthy of clinical application.
