摘要

目的:根据团队所做的参数调整,验证机械通气条件下早产儿潮气量(VT)的充分性,并与体重理想潮气量进行比较。方法:这是一项横断面研究,样本由agmenon magalh医院新生儿重症监护病房住院的胎龄<37周的PTNB组成。在60秒内收集了6次VT测量,并通过计算理想潮气量(VTi)来评估VT的充分性,公式为VTi = 4ml / kg x电流重量。结果:本组16例早产儿中,68.7%的早产儿在采集时电视内容不足。GA≥30周的PTNBs TV = 12.27±2.22mL,具有统计学意义。当校正体重时,GA <30的校正VT为9.34±4.63 mL / Kg,无统计学意义,但从临床角度来看很重要。结论:30周以下新生儿的VT暴露量大于理想体重范围。有了这个,就有可能确定连续监测室速的重要性,有利于更好的通气辅助,最大限度地减少肺损伤。

Adequacy of tidal volume offered during invasive mechanical ventilation in preterm infants
OBJECTIVE: To verify the adequacy of the tidal volume (VT) of the preterm newborn (PTNB) under mechanical ventilation according to the parameter adjustments made by the team and to compare it with the ideal tidal volume for the weight. METHOD: This is a cross-sectional study with a sample composed of PTNB with gestational age (GA) <37 weeks hospitalized in the Neonatal Intensive Care Unit of Hospital Agamenon Magalhães. Six VT measurements were collected for 60 seconds and the adequacy of the VT found was assessed by calculating the ideal tidal volume (VTi) using the formula Vti = 4ml / kg x current weight. RESULT: The sample of 16 premature infants, 68.7% had inadequate TV at the time of collection. PTNBs with GA above 30 weeks obtained a statistically higher TV (TV = 12.27 ± 2.22mL). When corrected for weight, those with GA <30 had a corrected VT of 9.34 ± 4.63 mL / Kg, not statistically significant, but mportante from a clinical point of view. CONCLUSION: It was found that PTNB below 30 weeks were exposed to VT greater than the ideal range for weight. With this, it is possible to identify the importance of continuous monitoring of the VT, favoring a better ventilatory assistance, minimizing lung injuries.
