jiān)測(cè)數(shù)據(jù)失真；術(shù)中如需使用電凝止血，盡量選擇雙極模式，減少單極電流對(duì)周邊設(shè)備的干擾。-防觸電：確保手術(shù)床、金屬托盤(pán)等接地良好，患者身體不接觸金屬物體（如手術(shù)床金屬欄），2.3手術(shù)環(huán)境優(yōu)化：“防火、防燃、防干擾”避免形成“straycurrent”（straycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurre2.3手術(shù)環(huán)境優(yōu)化：“防火、防燃、防干擾”ntstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstray2.3手術(shù)環(huán)境優(yōu)化：“防火、防燃、防干擾”currentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrent2.3手術(shù)環(huán)境優(yōu)化：“防火、防燃、防干擾”straycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstrayc2.3手術(shù)環(huán)境優(yōu)化：“防火、防燃、防干擾”urrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrents2.3手術(shù)環(huán)境優(yōu)化：“防火、防燃、防干擾”traycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycur2.3手術(shù)環(huán)境優(yōu)化：“防火、防燃、防干擾”rentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstr2.3手術(shù)環(huán)境優(yōu)化：“防火、防燃、防干擾”aycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurre2.3手術(shù)環(huán)境優(yōu)化：“防火、防燃、防干擾”ntstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstray2.3手術(shù)環(huán)境優(yōu)化：“防火、防燃、防干擾”currentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrent2.3手術(shù)環(huán)境優(yōu)化：“防火、防燃、防干擾”straycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstrayc2.3手術(shù)環(huán)境優(yōu)化：“防火、防燃、防干擾”urrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrents2.3手術(shù)環(huán)境優(yōu)化：“防火、防燃、防干擾”traycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrentstraycurrents
