Abstract

OBJECTIVE

to evaluate the ventilatory function by Peak Expiratory Flow (PEF) in the immediate pre and postoperative periods of patients undergoing elective surgical procedures in the upper abdomen.

METHODS

we conducted a prospective cohort study including 47 patients admitted to the Hospital Regional de Mato Grosso do Sul from July to December 2014, who underwent elective surgeries of the upper abdomen, and submiited to spirometric evaluation and measurement of PEF immediately before and after surgery.

RESULTS

of the 47 patients, 22 (46.8%) were male and 25 (53.20%) female. The mean preoperative PEF was 412.1±91.7, and postoperative, 331.0±87.8, indicating significant differences between the two variables. Men had higher PEF values than women, both in the pre and postoperative periods. There was a reasonable inverse correlation between age and decreased PEF. Both situations showed statistical significance (p<0.001). The group of smokers had lower PEF values both before and after surgery. The group of patients with comorbidities (hypertension and/or diabetes) showed lower PEF values both pre and postoperatively (p=0.005). In both groups, surgery resulted in a significant decrease in PEF (p<0.001). The type of surgery performed and the type of anesthesia did not show significant differences.

CONCLUSION

the variables most involved in decreased lung function were: advanced age, smoking and presence of comorbidities. However, there is no consistent evidence to suggest conducting routine spirometry in such patients.

OBJETIVO

avaliação comparativa da função ventilatória através do Pico de Fluxo Expiratório (PFE) no pré e pós-operatório imediatos de pacientes submetidos a procedimentos cirúrgicos eletivos do andar superior do abdome.

MÉTODOS: estudo prospectivo de coorte incluindo 47 pacientes internados no Hospital Regional de Mato Grosso do Sul de Julho à Dezembro de 2014, e que realizaram cirurgias eletivas do andar superior do abdome, e submetidos à avaliação espirométrica e aferição do PFE no pré e pós operatório imediatos.

RESULTADOS

dos 47 pacientes, 22 (46,8%) eram do sexo masculino, e 25 (53,20%) do sexo feminino. A média do PFE pré-operatório foi 412,1±91,7, e do pós-operatório de 331,0±87,8, indicando diferenças significantes entre as duas variáveis. O sexo masculino apresentou maiores valores de PFE do que o feminino, tanto no pré-cirúrgico quanto no pós-cirúrgico. Observou-se razoável correlação inversamente proporcional entre as variáveis idade e diminuição do PFE. Ambas as situações mostraram significância estatística (p<0,001). O grupo composto por fumantes apresentou menores valores de PFE tanto no pré como no pós-operatório. O grupo composto por portadores de co-morbidades (HAS e/ou DM) apresentou menores valores de PFE tanto no pré como no pós-operatório (p=0,005). Em ambos os grupos, o pós-operatório determinou uma diminuição significativa do PFE (p<0,001). O tipo de cirurgia realizada e o tipo de anestesia não mostraram diferenças significantes em relação ao PFE.

CONCLUSÃO: as variáveis mais implicadas na diminuição da função ventilatória, avaliadas através da PFE, foram: idade avançada, tabagismo e presença de comorbidades.

摘要

目的

通过峰值呼气流量(PEF)评估上腹部择期手术患者术前及术后即刻的通气功能。

方法

我们进行了一项前瞻性队列研究,纳入了2014年7月至12月在南马托格罗索州地区医院住院的47例患者,这些患者接受了上腹部择期手术,并在手术前后即刻接受了肺功能评估和PEF测量。

结果

47例患者中,22例(46.8%)为男性,25例(53.20%)为女性。术前PEF平均值为412.1±91.7,术后为331.0±87.8,表明这两个变量之间存在显著差异。男性在术前和术后的PEF值均高于女性。年龄与PEF降低之间存在合理的负相关。两种情况均具有统计学意义(p<0.001)。吸烟组在手术前后的PEF值均较低。合并症(高血压和/或糖尿病)组在术前和术后的PEF值也较低(p=0.0 =0.005)。在两组中,手术均导致PEF显著降低(p<0.001)。所进行的手术类型和麻醉类型在PEF方面未显示出显著差异。

结论

与肺功能降低最相关的变量为:高龄、吸烟和合并症。然而,没有一致的证据表明对此类患者进行常规肺功能检查是必要的。

目的

比较通过峰值呼气流量(PFE)对上腹部择期手术患者术前及术后即刻通气功能的评估。

方法

前瞻性队列研究,纳入2014年7月至12月在南马托格罗索州地区医院住院且接受上腹部择期手术的47例患者,并在手术前后即刻对其进行肺功能评估和PFE测定。

结果

47例患者中,22例(46.8%)为男性,25例(53.20%)为女性。术前PFE平均值为412.1±91.7,术后为331.0±87.8,表明这两个变量之间存在显著差异。男性在术前和术后的PFE值均高于女性。变量年龄与PFE降低之间存在合理的负相关。两种情况均具有统计学意义(p<0.001)。吸烟组在手术前后的PFE值均较低。合并症(高血压和/或糖尿病)组在术前和术后的PFE值也较低(p=0.005)。在两组中,术后均导致PFE显著降低(p<0.001)。所进行的手术类型和麻醉类型在PFE方面未显示出显著差异。

结论

通过PFE评估,与通气功能降低最相关的变量为:高龄、吸烟和合并症。
