2 透析的 開始時機 每週 KT/V < 2 GFR <10.5/min/1.73m2 DOQUI guideline 2

3 Before peritoneal dialysis
1. PD start 10 days to 2 weeks after catheter placement. 2. If PD started in < 10 days following catheter placement, do low-volume, supine dialysis. 3. Obtain baseline 24-hour urine collection for urea and creatinine clearance

4 Before peritoneal dialysis
4. Explain to patient/parents/caregivers that : The prescription will be individualized. Instilled volume almost increase over time. Their total solute clearance will be monitored IF RRF or peritoneal transport changes, their prescription may need to change as well.

5 1 month adjustment BSA, RRF, PET, S/S
First Prescription (Based on RRF, BSA) CAPD : (1.5L or 2L) x qid CCPD : 10 L + last bag (1L-2L) NIPD : 10 L 1 month adjustment BSA, RRF, PET, S/S CAPD(L, LA) CAPD(H, HA) WKt/V< WKt/V<2 WnCCr< WnCCr<60 NIDP WKt/V<2.2 WnCCr<66 CCPD WKt/V<2.1 WnCCr<63 換液次數增加 3次4次 or 4次5次 單袋灌注量增加 1.5L2L or 2L2.5L 增加白天 換液次數 1L-2L 一次或二次 CCPD HD

6 Initial prescription (1) Full dose to meet minimal total solute
clearance goal (2) Pt with a significant RRF, but Kt/V < 2.0 Incremental dosage of PD. (3) Based on BSA and residual renal function (4) During training, transporter type can be predicted from drain volume during a timed (4- hr) dwell with 2.5% glucose

7 Residual renal function
Renal GFR =1/2 (renal CCr + renal UreaCr) BSA = xBW(Kg)0.425xBH(cm)0.725

8 透析型態的選擇 CAPD = 白天由人力換透析液3-4次 晚上滯留 CCPD= 白天last bag滯留9小時,或CAPD換液1-2次
晚上由機器換透析液4-6次 NIDP = 晚上由機器換透析液4-6次 白天dry

9 GFR >2 ml/min A. If patient's lifestyle choice is CAPD:
BSA<1.7 m 4 x 1.5 L exchanges/day BSA 1.7 to 2 m2 4 x 2.0 L exchanges/day BSA>2.0 m  4 x 2.5 L exchanges/day

11 GFR >2 ml/min C. If patient's lifestyle choice is NIPD:
Used at the initiation of dialysis. Reserved for high or rapid transporters. Patients with significant RRF (and ability to diuresis), Nightly exchanges only (dry day)

12 2. GFR ≦2 ml/min A. If patient's lifestyle choice is CAPD:
BSA<1.7 m  4 x 2.0 L/day BSA 1.7 to 2.0 m2  4 x 2.5 L/day BSA >2.0 m  5 x 2.5 L/day (Consider use of a simplified nocturnal exchange device to achieve optimal dwell times and to augment clearance.)

13 2. GFR ≦2 ml/min B. If patient's lifestyle choice is CCPD:
BSA<1.7 m2 6 x 1.5 L (9hours/night) +1 L/d(last bag) BSA 1.7 to 2.0 m2 4 x 2.0 L (9 hours/night) L/day(last bag) BSA>2.0 m2  4 x 2.0 L (9 hours/night)+2.0 L/day (last bag) (可增加白天換液1-2次)

16 Adequate dialysis 1. Adequate solute removal ability
2. Adequate ultrafiltration

17 1st month adjustment Depend on Peritoneal equilibration test (PET)
Residual renal function (RRF) Body surface area (BSA) S/S weekly Kt/V and total nCCr Adjustment of dialysis dose

18 Peritoneal Equilibration Test (PET)
前一晚以Dialysate灌入腹內,存留8-12hrs 第二天早上，在PD Room以立姿引流全部 透析液20分(<25分)測引流量之容量。 以臥姿每10分注入2.5% Dialysate 2000ml。 每2分鐘 400ml速度，病人須在床上翻滾 以 利dialysate在腹腔內混合均勻。

19 Peritoneal Equilibration Test (PET)
Dialysate在全部注入後，為0分(0-dwell time) 立即引流200ml透析液，取10ml 送檢，其餘再注入腹內而後病人可以自由活動。 120分時，病人須引流灌注量1/10 之dialysate至透析液袋中搖晃均勻後，于透析液袋抽出10ml透析液，再將剩餘透析液注入腹腔內。 120分抽血送驗其glucose, Cr 值。 240分時，以立姿將dialysate全部引流20分 測其容積，並抽10ml dialysate送驗。

20 Peritoneal equilibration test (PET)

35 Adequate ultrafiltration

36 簡單UFF 之定義 病人即使每天使用2-3袋的高濃度 (4.25%)之透析液, 而仍會發生水腫. 即使限水亦無法達到乾體重.

37 超過率能力不足 S/S -高血壓 水腫 -使用高濃度透析液的次數增加

38 Management of Ultrafiltration inadequate
↑dialysate 總量 or  ↑換袋次數  ↑單袋灌注量  ↑Dextrous 濃度( 1.25%2.5%4.25%)  Extraneal (Icodextrin)  限制水份攝取  urine <500cc/day Transamin1#Bid

39 -高血壓 水腫 -使用高濃度透析液的次數增加 First prescription  ↑dialysate 總量 or  ↑換袋次數
CAPD : (2L or 1.5L ) x qid CCPD : 10 L +last bag (1L-2L) NIPD : 10 L -高血壓 水腫 -使用高濃度透析液的次數增加  ↑dialysate 總量 or  ↑換袋次數  ↑單袋灌注量  ↑Dextrous 濃度( 1.25%2.5%4.25%)  Extraneal (Icodextrin)  限制水份攝取  urine <500cc/day Transamin1#Bid

40 體液過量 導管問題 透析液漏出 遵醫性不良 灌注2公升之透析液 24H urine 流出量不變 檢查流出量 流出量↓ 下降 真正失去UF
RFF減少 PET 上升 下降 不變 1.淋巴吸收上升 2.透析液滲漏 3.導管問題 4.經細胞穿透力下降 Type I UFF 新生的腹膜炎 Type II UFF 1.硬化性腹膜炎 2.粘連

41 Type I UFF 70%-80% Peritonitis  ↑transport effect
(D/PCr ↑, D/D0 glucose↓) Reversible after 1 month

42 Type II UFF 較少 Sclerosing peritonitis and peritoneal adhesion
腹膜表面積減少, 穿透性下降 同時會出現UFF 及inadequate solute transport

43 Type III UFF High lymphatic absorption rate Uncommon

44 Type IV UFF Aquaporin deficiency Rare
↓Water channels or ↓ ultra-small pore deficient crystalloid-induced UF Dx :<400ml UF with 4.25%PET lack of Na sieving early in the dwell Tx : colloid osmotic agents (icodextrin)

45 Type I UFF 滲透性增加 避免夜間留存太久 若有尿 可加 lasix 改成NPD 暫時HD or 改用icodetran Type II UFF 硬化性腹膜炎 黏連 試tidal PD 轉HD 便秘 軟便劑 高纖食物 疝氣 滲漏 手術修復 暫停PD 導管位置不良 校正導管位置 用腹腔鏡 Type III UFF 淋巴吸收增加 無有效治療方法

46 Icodextrin 7.5% Glucose polymer MW=16800 Osmolality 285mOsm/kg
UF occurred by colloid osmosis via small pores No UF via ultra pores, through which glucose mainly acts, so no sodium sieving

47 腹膜透析轉血液透析的適應症 適應症 :無法達適當腹膜透析量 無法達到適當水分控制、 無法控制的高血脂症、 無法接受的高腹膜炎發生率或
適應症 :無法達適當腹膜透析量 無法達到適當水分控制、 無法控制的高血脂症、 無法接受的高腹膜炎發生率或 其他腹膜透析併發症、技術問題、 無法矯正的營養不良．

48 Pitfalls in Prescription of PD
Noncompliance Patients on Standard CAPD are: (a) inappropriate dwell times (b) failure to ↓ dialysis dose to compensate for loss of RRF; (c) inappropriate instilled volume (d) multiple rapid exchanges and 1 very long dwell (e) inappropriate selection of dialysate glucose

49 Pitfalls in Prescription of PD
Patients on cycler therapy. =The drain time may be inappropriately long (> 20 min). =Inappropriately short dwell times =Failure to augment total dialysis dose with a daytime dwell ("wet" day vs "dry" day) could also result in underdialysis. =Inappropriate selection of dialysate glucose may not allow maximization of UF, resulting in less total clearance.
