We present the nurse's procedure for routine measurement of intraperitoneal hydrostatic pressure (IPP). It is very easy, simple, and safe. We measure the height of dialysis fluid in the peritoneal dialysis (PD) line before drainage. The level of the column of dialysate is measured with a scale, expressed in centimeters of water. The patient rests in a strictly horizontal position and the zero level is set at the medial axillary line. Two measurements are taken: one when breathing in and the other when breathing out. The IPP must be measured at atmospheric pressure without any counterpressure. Therefore, two techniques exist, depending on the geometry of the PD system. With disconnect systems, there is no counterpressure in the line and the empty drainage bag. With nondisconnect systems, there is always a counterpressure in the line because an air inlet is necessary. The measurement of IPP is an important element in the medical prescription of intraperitoneal volumes for adequate dialysis and to prevent mechanical complications. Normal values are established in patients undergoing CAPD treatment: IPP insp. = 14 +/- 2 cmH2O and IPP exp. = 12 +/- 2 cmH2O.
我们介绍护士进行腹腔内静水压（IPP）常规测量的操作步骤。该操作非常简便、安全。我们在引流前测量腹膜透析（PD）管路中透析液的高度。用刻度标尺测量透析液柱的高度，以厘米水柱表示。患者需处于严格的水平位置，零点设置在腋中线。测量两次：一次在吸气时，另一次在呼气时。IPP必须在大气压下测量，且无任何反压。因此，根据PD系统的结构存在两种技术。对于可断开连接的系统，管路和空的引流袋中没有反压。对于不可断开连接的系统，由于需要进气口，管路中始终存在反压。IPP的测量是确定腹腔内合适透析液量的医学处方以及预防机械并发症的重要因素。接受持续性非卧床腹膜透析（CAPD）治疗的患者的正常数值为：吸气时IPP = 14±2 cmH₂O，呼气时IPP = 12±2 cmH₂O。
