ABSTRACT

Objective To assess the safety and feasibility of video electroencephalographic (VEEG) monitoring in preterm infants and critically ill neonates in neonatal intensive care unit (NICU). Method From December 2017 to June 2018, high risk infants were prospectively enrolled and received VEEG monitoring in our NICU. Their basic information, adverse events and disturbances of any procedure during VEEG monitoring were collected by specially-trained nurses. Result A total of 245 times of VEEG were recorded. The average gestational age (GA) was (32.1 ± 3.6) weeks, the birth weight (BW) was (1879 ± 757) g, the corrected GA (cGA) at VEEG monitoring was (33.8±3.3) weeks, and the average weight at VEEG monitoring was (2008±716) g. The earliest cGA at VEEG monitoring was 25+5 weeks, and the lowest weight at VEEG monitoring was 520 g. The average monitoring duration was (4.9±2.4) h, ranging from 3 to 20 hours. During VEEG monitoring, 80 cases (32.7%) received noninvasive ventilation, 43 cases (17.6%) mechanical ventilation. The adverse events during electrodes placement were oxygen desaturation in 8(3.3%) cases. During VEEG monitoring, local skin erythema were found in 4 cases (1.6%), and electrodes displacement in 2(0.8%) cases. The disturbances of any clinical procedures were reported in 18(7.3%) cases. No severe adverse events such as displacement of endotracheal tube nor events requiring cardiopulmonary resuscitation occurred during VEEG monitoring. Conclusion It is feasible and safe for trained NICU nurses to place electrodes for high risk neonates.

ABSTRACT

Objective To study the video-electroencephalography (vEEG) background activities of very premature infants within the first 7 days after birth.Method The inclusion criteria were gestational age (GA) within 31 weeks and bedside vEEG monitoring within first 7 days of birth.Those with severe cranial ultrasound (CUS) findings,refused treatment,dead and with seizures on vEEG were excluded.The clinical information of included cases were reviewed and the continuity and sleep-wake cycle (SWC) on their EEG background activities were analysed.Result From June 2017 to April 2018,a total of 56 cases were included.Their GA were (29.4 ± 1.6) weeks,and birth weight were (1 306 ± 316) g.A total of 31 cases were diagnosed with asphyxia(1 min Apgar score less than 8),and no one with 5 min Apgar score below 5.Their umbilical artery blood pHs were 7.29 ± 0.07.Their first CUS and the CUS at corrected gestational age (cGA) full term were all within the normal range.The Gesell neurological assessment at cGA 6 months were all within the normal range.As the cGA increased,the continuity of EEG background activities became more continuous as the normal continuous/discontinuous pattern.The 95% confidence interval of max interburst interval was 95 s.The SWC first occurred at GA 26 w,but was immature,then became mature as the cGA increased.Conclusion The EEG background activity analysis of relatively normal very premature infants within first week shows that interburst interval can be longer than the previous report,and the SWC first appear at GA 26 w.

ABSTRACT

OBJECTIVE: To study the clinical characteristics of epileptic patients with synchronous occipital and frontopolar spikes phenomenon. METHODS: The clinical data,EEG features of patients with synchronous occipital and frontopolar spikes phenomenon were retrospectively reviewed. RESULTS: Totally 34 male and 21 female patients had synchronous occipital and frontopolar spikes. Ages at the time of recording the synchronous occipital and frontopolar spikes phenomenon ranged from 2 years 6 months to 14 years with the median age of 6 years 6 months. In the total 55 patients,12 patients had contralateral synchronous discharges,12 patients had ipsilateral synchronous,17 patients had bilateral synchronous discharges,7 patients had bilateral synchronous discharges tending to contralateral synchronously,and 7 patients had bilateral synchronous discharges tending to ipsilateral synchronously. Occipital preceded frontopolar discharges in 42 patients. Frontopolar preceded occipital discharges in 3 patients. The phase difference between the occipital and frontopolar spikes could not be distinguished in 10 patients. Based on the etiology and diagnoses,there was Panayiotopoulos syndrome in 33 patients,epilepsy with structural abnormality in 13 patients,secondary epilepsy due to immune encephalitis in 1 patient,epilepsy accompanied by inborn error of metabolism in 2 patients and epilepsy with unknown etiology in 6 patients. CONCLUSION: The synchronous occipital and frontopolar spikes phenomenon usually appears during childhood or develops from other discharge patterns in infancy stage. The synchronous occipital and frontopolar spikes phenomenon can be ipsilateral synchronous or contralateral synchronous discharges. The occipital spikes preceded frontopolar spikes in most patients. The synchronous occipital and frontopolar spikes phenomenon is mostly found in Panayiotopoulos syndrome,but it is also found in epilepsy with different etiologies.
