手術後の肺活量（VC）が咳嗽力（PCF）に影響を及ぼすことは明らかだが，最大発声持続時間（MPT）で評価される声門閉鎖機能低下がPCF に及ぼす影響は明らかとなっていない．本研究では呼吸器外科手術後の患者28 例においてMPT とPCF の関係を明らかにすることを目的とし，手術後1 日目〜5 日目にPCF，MPT，VC を測定した．手術後5 日目までPCF およびMPT は，手術前と比較し有意に低下した（p <0.05）． またPCF とMPT の回復率には手術後1 日目のみに相関関係を認めた（r= 0.53，p <0.05）．PCF とVC の回復率は手術後1 日目〜5 日目まで相関を認めた（r = 0.41-0.27，p <0.05）．手術後の声門閉鎖機能低下が咳嗽力に及ぼす影響は，人工呼吸器離脱後１日目までで，その後はVC の影響を強く受けると考えられた．

The vital capacity（ VC） after thoracic surgery affects peak cough flow（ PCF）.　However, the influence of glottic closure deterioration evaluated by maximum phonation time （MPT） on PCF is not clear. We clarified the relationship between coughing and vocal cord function in 28 patients after thoracic surgery. We measured the PCF, MPT, and VC on postoperative days 1 to 5. On postoperative day 1, the mean PCF decreased to 58.0% and the mean MPT decreased to 62.5%. The mean PCFs and MPTs on postoperative days 1 to 5 were significantly lower than the preoperative PCF and MPT, respectively （p < 0.05）. There was a positive correlation between the rates of change in the PCF and MPT only on postoperative day 1 （r = 0.53, p < 0.05）. There was also a positive correlation between the rates of change in the PCF and VC on postoperative days 1 to 5 （r = 0.41–0.27, p < 0.05）. Cough intensity was affected by the vocal cord function on postoperative day 1. However, after postoperative day 2, the cough intensity was not influenced by the vocal cord function. Declining glottal closure function（ vocal cord function） immediately after surgery affects the cough intensity and vocal function. The influence of reduction in glottic closure function after surgery on coughing decline was observed up to 1 day after the withdrawal of ventilatory support. After the secondpostoperative day, the PCF was strongly influenced by the VC.
