Rapidly decompressing the abdomen drops intra-abdominal pressure and causes reflex splanchnic arterial vasodilation, dropping effective arterial blood volume, spiking plasma renin and aldosterone levels 2 to 6 days later, and precipitating rapid re-accumulation of tense ascites, severe dilutional hyponatremia, Hepatorenal Syndrome (AKI), hepatic encephalopathy, and death.
If any patient with cirrhosis and ascites develops fever, belly pain, new confusion/drowsiness, reduced urine output, or shortness of breath from a tense swollen abdomen, call your local inomero z'ivyihutirwa immediately. Also review our sibling guides on hepatic encephalopathy grade 3 and 4 liver coma, asterixis, and lactulose enema, esophageal varices rupture, cirrhosis bleeding, and hepatic encephalopathy, na appendicitis, ruptured appendix, peritonitis, and right lower quadrant pain.
Ivyo ubikore ubu¶
- Perform a Bedside Ultrasound-Guided Diagnostic Paracentesis Within 6 Hours (Ideally Within 1 to 2 Hours) on EVERY Patient with Cirrhosis and Ascites Admitted to the Hospital, Even If They Have Zero Abdominal Pain and Zero Fever. Call 911 in the United States and Canada, 999 in the United Kingdom, 112 across the European Union, 000 in Australia, or consult our global directory of inomero z'ivyihutirwa. Up to 15 to 30 percent of all hospitalized cirrhotic patients with ascites have active SBP upon admission, often presenting only with subtle confusion (hepatic encephalopathy) or a rising serum creatinine.
- NEVER Delay a Diagnostic Paracentesis to Give Fresh Frozen Plasma (FFP) or Platelets for an Elevated INR or Low Platelet Count.
- A universal hospital error is delaying a diagnostic ascitic tap for 6 to 12 hours to transfuse FFP because a cirrhotic patient has an \(\text{INR}\) of \(2.2\) or platelets of \(45,000/\text{\mu L}\).
- AASLD, EASL, and BSG Guidelines state unequivocally: Cirrhotic coagulopathy is rebalanced; the risk of significant bleeding from an ultrasound-guided diagnostic paracentesis is less than \(0.2\%\), and neither an elevated INR nor thrombocytopenia is a contraindication to paracentesis (the only exclusions are clinically evident fibrinolysis or disseminated intravascular coagulation [DIC]). Use bedside ultrasound with Color Doppler to target the Left Lower Quadrant (where the abdominal wall is thinner and the cecum is avoided) and stay at least \(5\text{ cm}\) lateral to the midline to avoid the inferior epigastric artery.
- Calculate the Ascitic Fluid Absolute Polymorphonuclear Leukocyte (PMN / Neutrophil) Count AND Inoculate \(10\text{ mL}\) of Ascitic Fluid Directly into Aerobic and Anaerobic Blood Culture Bottles at the Bedside:
- The Diagnostic Threshold for SBP: An ascitic fluid Absolute PMN (Neutrophil) Count \(\ge 250\text{ cells/mm}3\) (\(0.25 \times 109\text{/L}\)) confirms Spontaneous Bacterial Peritonitis and mandates immediate empiric intravenous antibiotics + IV albumin without waiting 48 hours for culture results.
- Bloody Tap Correction Formula: If a traumatic tap introduces red blood cells (\(\text{RBCs}\)) into the fluid, subtract \(1\text{ PMN}\) for every \(250\text{ RBCs/mm}3\) to get the true corrected PMN count.
- Why Bedside Blood Culture Bottles Are Mandatory: Sending ascitic fluid to the lab in a plain sterile syringe or cup yields positive cultures in less than \(40\%\) of SBP cases (because SBP has a very low bacterial colony count of \(\approx 1\text{ organism/mL}\)). Inoculating \(10\text{ mL}\) of ascitic fluid directly into aerobic and anaerobic blood culture bottles at the bedside boosts culture sensitivity above \(80\%\).
- Administer Empiric Intravenous Antibiotics Immediately After the Tap:
- Community-Acquired SBP (No Septic Shock, No Recent Beta-Lactam Exposure): Administer Intravenous Ceftriaxone \(2\text{ grams}\) IV every 24 hours (or IV Cefotaxime \(2\text{ grams}\) every 8 hours) for 5 to 7 days.
- Nosocomial / Healthcare-Associated SBP, Septic Shock, or Recent Hospitalization: Because 30 to 40 percent of hospital-acquired SBP is caused by Extended-Spectrum Beta-Lactamase (ESBL) Gram-negatives or Enterococcus / MRSA, start broad-spectrum Intravenous Meropenem (\(1\text{ g}\) IV every 8 hours) or Piperacillin-Tazobactam (\(4.5\text{ g}\) IV every 6 to 8 hours) PLUS Vancomycin or Daptomycin (or Tigecycline in VRE/MDRO areas).
- Administer Mandatory Intravenous \(25\%\) Human Albumin Using the Sort Protocol (\(1.5\text{ g/kg}\) on Day 1 + \(1.0\text{ g/kg}\) on Day 3) and HOLD All Beta-Blockers, Diuretics, and NSAIDs.
- In the landmark Sort et al. (NEJM 1999) trial, adding Intravenous \(25\%\) Human Albumin, \(1.5\text{ grams/kg}\) of body weight within 6 hours of SBP diagnosis on Day 1 (maximum \(100\text{ g}\)), followed by \(1.0\text{ gram/kg}\) on Day 3 (maximum \(100\text{ g}\)), slashed the rate of Hepatorenal Syndrome from \(30\%\) down to \(10\%\) and reduced in-hospital mortality from \(29\%\) down to \(10\%\). (Especially critical if baseline Serum Creatinine \(> 1.0\text{ mg/dL}\) [\(88\text{ \mu mol/L}\)], BUN \(> 30\text{ mg/dL}\), or Total Bilirubin \(> 4.0\text{ mg/dL}\) [\(68\text{ \mu mol/L}\)]).
- Immediately HOLD Non-Selective Beta-Blockers (Propranolol, Nadolol, Carvedilol), Diuretics (Furosemide, Spironolactone), ACE Inhibitors/ARBs, and Aminoglycosides during active SBP: beta-blockers blunting cardiac output during SBP splanchnic vasodilation markedly increase the risk of Hepatorenal Syndrome and death.
- Prevent Post-Paracentesis Circulatory Dysfunction (PPCD) During Any Large-Volume Paracentesis (\(> 5\text{ Liters}\) Removed): Infuse \(6\text{ to }8\text{ Grams}\) of \(25\%\) IV Albumin per Liter Removed.
- Never perform a Large-Volume Paracentesis (LVP \(> 5\text{ L}\)) during active Spontaneous Bacterial Peritonitis (draining large volumes during active SBP accelerates acute kidney injury; perform only a small diagnostic tap [\(30\text{ to }50\text{ mL}\)] until SBP is treated, unless tense ascites is causing immediate respiratory failure).
- Whenever performing an elective or urgent Large-Volume Paracentesis (\(> 5\text{ L}\) removed in sterile ascites), infuse \(6\text{ to }8\text{ grams}\) of \(25\%\) Intravenous Human Albumin for every liter of ascites removed (for example, if \(8\text{ liters}\) are drained, infuse \(48\text{ to }64\text{ grams}\) [\(200\text{ to }250\text{ mL}\) of \(25\%\) Albumin] IV during or immediately after the procedure).
How to Avoid Operating on SBP, and How to Avoid Missing a Perforated Bowel (Runyon's Criteria for Secondary Bacterial Peritonitis)
Performing an exploratory laparotomy on a decompensated cirrhotic patient who actually has Spontaneous Bacterial Peritonitis (SBP) carries an 80 percent surgical mortality rate from liver failure and bleeding. Conversely, treating a perforated duodenal ulcer, perforated appendix, or perforated diverticulitis (Secondary Bacterial Peritonitis) inside an ascitic belly with medical ceftriaxone alone without surgery is 100 percent fatal. Use Runyon's Ascitic Fluid Criteria on every tap: suspect Secondary Bacterial Peritonitis (Surgical Perforation) and order an immediate Abdominal CT with IV and Oral/Rectal Contrast if the ascitic fluid shows \(\text{PMN} \ge 250/\text{mm}3\) PLUS at least TWO of the following THREE laboratory signs: 1. Ascitic Fluid Total Protein \(> 1.0\text{ g/dL}\) (\(10\text{ g/L}\)); 2. Ascitic Fluid Glucose \(< 50\text{ mg/dL}\) (\(2.8\text{ mmol/L}\)); 3. Ascitic Fluid LDH \(>\) Upper Limit of Normal for Serum LDH (or polymicrobial flora/fungi seen on Gram stain).

Complete Diagnostic Classification of Ascitic Fluid Infections: SBP vs. Culture-Negative Neutrocytic Ascites vs. Bacterascites vs. Secondary Peritonitis¶
Every ascitic fluid tap must be classified into one of five distinct entities based on the Corrected Absolute PMN Count (\(\text{Total WBC} \times \%\text{Neutrophils}\)), Bedside Blood-Culture Bottle Result, and Runyon's Biochemistry:
| Urugero rw'amazi y'umubiri | Igitigiri ca PMN cakosowe (\(\umwandiko{utugingo ngengabuzima/mm}3\)) | Ascitic Fluid Bacterial Culture Result | Ascitic Protein, Glucose & LDH (Runyon's Criteria) | Clinical Meaning & Mandatory Emergency Action |
|---|---|---|---|---|
| 1. Classic Spontaneous Bacterial Peritonitis (SBP) | \(\ge 250/\text{mm}3\) | Positive for a SINGLE organism (E. coli, Klebsiella pneumoniae, or Streptococcus pneumoniae) | Protein usually \(< 1.0\text{ g/dL}\); Glucose \(\ge 50\text{ mg/dL}\); LDH \(<\) Serum ULN. | Active SBP: Start IV Ceftriaxone \(2\text{ g}\) q24h (or Meropenem if nosocomial) + IV \(25\%\) Albumin (\(1.5\text{ g/kg}\) Day 1, \(1.0\text{ g/kg}\) Day 3). |
| 2. Culture-Negative Neutrocytic Ascites (CNNA) | \(\ge 250/\text{mm}3\) | Negative (often due to prior antibiotic dose or poor culture technique; rule out pancreatitis, peritoneal carcinomatosis, or tuberculous peritonitis) | Same as Classic SBP (low protein, normal glucose, low LDH). | Treat 100% Identically to Classic SBP: Carries the exact same mortality and hepatorenal risk as culture-positive SBP; give IV Ceftriaxone + IV Albumin. |
| 3. Monomicrobial Non-Neutrocytic Bacterascites (MNB) | \(< 250/\text{mm}3\) | Positive for a SINGLE organism (detected 24 to 48 hours later when lab calls with positive blood culture bottle) | Normal / baseline transudative cirrhotic ascites. | Two Paths: - If Symptomatic (fever, pain, confusion/HE, or AKI): Treat immediately as full SBP. - If Completely Asymptomatic: Repeat diagnostic paracentesis immediately (60% clear spontaneously; if repeat \(\text{PMN} \ge 250\) or culture stays positive, treat as SBP). |
| 4. Secondary Bacterial Peritonitis (Perforated Viscus or Abscess) | \(\ge 250/\text{mm}3\) (often \(> 1,000\text{ to }10,000/\text{mm}3\)) | Polymicrobial (multiple enteric Gram-negatives + anaerobes + Enterococcus or Candida) | Runyon's Positive (\(\ge 2\) of 3): 1. Protein \(> 1.0\text{ g/dL}\) 2. Glucose \(< 50\text{ mg/dL}\) 3. LDH \(>\) Serum ULN (Also check Ascitic CEA \(> 5\text{ ng/mL}\) or Alk Phos \(> 240\text{ U/L}\) for hollow viscus perforation). |
SURGICAL EMERGENCY: Order STAT Abdominal/Pelvic CT with contrast, add anaerobic coverage (IV Piperacillin-Tazobactam or Ceftriaxone + Metronidazole), and consult General Surgery immediately. |
| 5. Polymicrobial Bacterascites (Needle Bowel Puncture) | \(< 250/\text{mm}3\) | Polymicrobial (ibinyabuzima vyinshi vyo mu mara + ibibumbano vy’umuyaga/ibintu biva mu mara) | Normal baseline PMN count because the paracentesis needle accidentally entered a loop of bowel. | Most resolve without surgery; repeat paracentesis from opposite quadrant and cover with broad-spectrum IV antibiotics (Ceftriaxone + Metronidazole) if symptoms develop. |
Step-by-Step Hospital Protocol for Performing Ultrasound-Guided Paracentesis, Treating SBP, and Preventing PPCD¶
Step 1: Safe Ultrasound-Guided Technique (The Left Lower Quadrant & "Z-Track" Method)¶
- Why the Left Lower Quadrant (LLQ) Is Preferred Over the Right Lower Quadrant:
- The abdominal wall in the Left Lower Quadrant (\(2\text{ fingerbreadths}\) [\(3\text{ cm}\)] cephalad and \(2\text{ fingerbreadths}\) medial to the anterior superior iliac spine [ASIS]) is thinner and has a deeper pool of ascitic fluid than the midline, and avoids the distended cecum in the Right Lower Quadrant (which is often dilated with gas from lactulose therapy) as well as right-upper-quadrant hepatomegaly.
- Mandatory Bedside Ultrasound + Color Doppler Check:
- Identify the deepest pocket of free-floating anechoic fluid free of bowel loops or omentum.
- Use Color Doppler to locate and avoid the Inferior Epigastric Artery (which runs vertically inside the rectus sheath \(4\text{ to }8\text{ cm}\) lateral to the umbilicus) and any dilated caput medusae / abdominal wall portosystemic collateral veins.
- The "Z-Track" Needle Insertion Technique (Prevents Post-Tap Ascitic Fluid Leak):
- After sterile chlorhexidine prep and \(1\%\) lidocaine wheal down to the peritoneum, pull the skin \(2\text{ centimeters}\) caudally (downward) with your non-dominant hand while advancing the paracentesis needle perpendicular to the abdominal wall, aspirating continuously until peritoneal fluid enters the syringe. When the needle is withdrawn at the end of the tap, the skin slides back to its original position, creating an offset "Z-track" seal so ascitic fluid does not leak onto the bed. (If a persistent post-paracentesis ascitic leak ever occurs, place a sterile ostomy bag over the site to quantify losses or close the skin pinhole with a single figure-of-eight suture or tissue adhesive while having the patient lie on the opposite side).
Step 2: The Complete SBP Hospital Treatment Bundle (Antibiotics, Albumin, Medication Hold, and 48-Hour Tap Check)¶
| Component of SBP Bundle | Exact Regimen & Timing | Clinical Rationale & Guideline Evidence |
|---|---|---|
| 1. Empiric IV Antibiotics (Within 1 Hour of Diagnosis) | - Community-Acquired SBP: IV Ceftriaxone \(2\text{ g}\) every 24 hours (or IV Cefotaxime \(2\text{ g}\) every 8 hours) for 5 to 7 days. (If severe beta-lactam anaphylaxis: IV Levofloxacin \(500\text{ mg}\) q24h or IV Ciprofloxacin \(400\text{ mg}\) q12h ONLY if patient was NOT already taking fluoroquinolone SBP prophylaxis; otherwise use Aztreonam + Vancomycin). - Nosocomial / ICU / Septic Shock SBP: IV Meropenem \(1\text{ g}\) q8h (or Piperacillin-Tazobactam) + IV Vancomycin or Daptomycin. |
A 5-day course of third-generation cephalosporin is equal in efficacy to a 10-day course in uncomplicated SBP. Strictly avoid Aminoglycosides (Gentamicin, Tobramycin, Amikacin), which cause catastrophic nephrotoxicity in cirrhosis. |
| 2. Intravenous 25% Human Albumin (Sort Protocol) | - Day 1 (Within 6 Hours of Diagnosis): \(1.5\text{ grams/kg}\) of \(25\%\) Human Albumin IV (max \(100\text{ g}\), infused over 4 to 6 hours). - Day 3 (48 Hours Later): \(1.0\text{ gram/kg}\) of \(25\%\) Human Albumin IV (max \(100\text{ g}\)). |
Proven by Sort et al. (NEJM) to cut Type-1 Hepatorenal Syndrome from \(30\%\) to \(10\%\) and reduce mortality from \(29\%\) to \(10\%\). Highest benefit when Serum Creatinine \(> 1.0\text{ mg/dL}\), BUN \(> 30\text{ mg/dL}\), or Bilirubin \(> 4.0\text{ mg/dL}\). (Use \(25\%\) concentrated hyperoncotic albumin, not \(5\%\) albumin in saline, to avoid sodium/fluid overload; infuse slowly if underlying heart failure or portopulmonary hypertension is present). |
| 3. Mandatory Medication Audit (Hold Beta-Blockers, Diuretics & PPIs) | - STOP Non-Selective Beta-Blockers (Propranolol, Nadolol, Carvedilol) immediately during active SBP (permanently discontinue if SBP is complicated by hypotension [\(\text{SBP} < 90\text{ mmHg}\) or \(\text{MAP} < 65\text{ mmHg}\)] or Hepatorenal Syndrome). - HOLD Furosemide & Spironolactone until SBP and AKI resolve. - Discontinue Unnecessary Proton Pump Inhibitors (PPIs) (omeprazole, pantoprazole) unless there is an active peptic ulcer/GI bleed. |
Mandorfer et al. (Gastroenterology) proved that continuing beta-blockers during active SBP prevents compensatory tachycardia, doubling the rate of Hepatorenal Syndrome and mortality. Chronic PPIs destroy the gastric acid barrier and triple recurrent SBP risk. |
| 4. When to Perform a 48-Hour Repeat Diagnostic Paracentesis | Repeat a diagnostic tap at 48 hours if the patient fails to improve clinically OR has atypical/nosocomial SBP. | In properly treated SBP, the 48-hour ascitic PMN count must drop by at least \(25\%\) from baseline. If the 48-hour PMN count is static or rising, immediately broaden antibiotics for MDRO / ESBL / Enterococcus AND order a CT scan to rule out Secondary Surgical Peritonitis. |
| 5. Lifelong Secondary Oral Antibiotic Prophylaxis Before Discharge | Start Oral Trimethoprim-Sulfamethoxazole (Bactrim DS, 1 double-strength tablet [\(160/800\text{ mg}\)] PO once daily) OR Oral Ciprofloxacin \(500\text{ mg}\) PO once daily (or Norfloxacin \(400\text{ mg}\) PO daily where available) upon completing IV therapy, plus Urgent Liver Transplant Evaluation. | Without daily oral prophylaxis, 70 percent of SBP survivors suffer a recurrent episode within 1 year, and 1-year survival after a first episode of SBP is only \(30\%\text{ to }50\%\) without liver transplantation. |
Step 3: Performing Large-Volume Paracentesis (LVP) Safely and Preventing Post-Paracentesis Circulatory Dysfunction (PPCD)¶
When a patient has sterile tense ascites (\(\text{PMN} < 250/\text{mm}3\)) causing diaphragmatic splinting, dyspnea, or early satiety: 1.

Ibibazo bikunda kubazwa¶
Ni kuki abarwayi bose bafise indwara y’ibihaha iterwa n’imigera (SBP) ishobora gutuma umuntu apfa, bashika ku gice c’abarwayi bose badafise ububabare bwo mu nda n’umuriro?¶
Ku muntu atagira indwara y’igitigu, indwara yo mu nda (nk’aho umugereka waturitse) ituma amara avyimba akora ataco akora ku ruhome rw’inyuma rw’inda (peritoneum pariétal) rushobora gutera ububabare, bigatuma umuntu agira ububabare bubabaje cane kandi akagira inda ikomeye kandi imeze nk’urubaho igihe cose umuganga akanda. Ku murwayi arwaye cirrhose n’ascite, litiro 5 gushika kuri 15 z’amazi zikora nk’igipfukisho c’amazi gitandukanya mu buryo bw’umubiri ingingo z’imbere n’uruhome rw’inyuma rw’inda, bikabuza gutera imbere mu nda no gupfuka ububabare bwo mu nda n’ububabare bwo gusubira inyuma. Muri ico gihe nyene, abarwaye indwara ya cirrhose baragira ingorane zo gukingira umubiri, kandi ubushuhe bwo mu mubiri buraba buke, ni co gituma kenshi badashobora gutera umuriro. Aho kugira ububabare canke umuriro, ikimenyetso cabo ca mbere nyene c’indwara ya SBP akenshi ni ugutera umuvurungano mu buryo butunguranye (Hepatic Encephalopathy), umuvuduko w’amaraso ugabanuka canke amafyigo adakora neza, ni co gituma abaganga bategerezwa gutera urushinge mu nda y’umurwayi wese w’indwara ya cirrhose yinjiye mu bitaro.
Ni kubera iki ari ikosa riteye akaga kurindira ko umuntu aterwa amaraso y’umubiri (FFP) canke amaraso y’umubiri imbere y’uko akora igikorwa co gupima indwara?¶
Abarwayi bafise indwara ya cirrhose iteye imbere hafi y’igihe cose barasuzumwa ukuntu amaraso ashobora gutera (INR iri hejuru cane kuva kuri 1,8 gushika kuri 2,5) be n’uko utugingo ngengabuzima dutera (40.000 gushika ku 70.000) kubera ko igitigu cabo gikora ibintu bikeyi bituma amaraso atera kandi umutsi wabo wagutse ugafata utugingo ngengabuzima. Ariko rero, ubuhinga bwo kumenya amaraso bwo muri iki gihe bugaragaza ko abarwaye indwara ya cirrhose na bo nyene bakora ibintu bikeyi bigabanya amaraso (Proteine C na antithrombine), ku buryo amaraso yabo "asubira gukomera." Ivyigwa vyakozwe ku bihumbi vy’abaganga bakoresheje ubuhinga bwa ultrasound vyerekana ko ingorane zo kuva amaraso ziri munsi ya 1 kuri 500 ataco zifatiye ku INR canke igitigiri c’amaraso, mu gihe gutevya amasaha 6 gusa gufata amaraso n’imiti yo gupima indwara kugira ngo umuntu afungure no guterwa amaraso adakenewe bituma umuntu apfa kubera SBP septic per centar20.
Ni gute Albumine yo mu mutsi ikiza ubuzima muri SBP mu gihe Ceftriaxone isanzwe yica iyo migera?¶
Naho umuti witwa Ceftriaxone ushirwa mu mutsi wica ningoga imigera ya E. coli canke Klebsiella iri mu mazi y’umubiri, iyo migera iriko irapfa irarekura ubumara bwo mu mubiri (lipopolysaccharide) butera guturika cane kw’umugera wa nitric oxide mu mitsi y’amaraso yo mu mara. Iyo nitric oxide ituma imitsi yose y’amaraso yo mu nda ifunguka cane, igatuma amaraso akoranya mu mara maze igatuma amafyigo asonza amaraso, ivyo bikaba bituma abarwayi 30 kw’ijana bagira indwara y’amafyigo (Hepatorenal Syndrome) yica. Gutera Albumine y’umuntu yihariye 25% ku musi wa mbere (1,5 g/kg) no ku musi wa gatatu (1,0 g/kg) bikora ibintu bibiri bishobora gukiza ubuzima amazi y’umunyu IV adashobora gukora: umuvuduko wayo ukomeye w’indwara y’ibicurane ufata amazi imbere mu mitsi yo hagati kugira ngo amafyigo agume apfutse, kandi albumine ba neutraliz direct igafatanya amazi . endotoxin, nitric oxide be n’ibitera umururumba, ivyo bikaba bigabanya igitigiri c’abantu bapfa n’ibice bibiri vya gatatu.
Bigenda gute iyo umuganga akuye litiro 8 z’amazi mu nda yavyimvye (Paracentèse de grande volume) atamuhaye IV Albumine?¶
Iyo umuganga avuye amazi arenga litiro 5 y’amazi y’umubiri (tense ascitic fluid) mu gihe kimwe atamuha Albumine 25% mu mutsi, ukugabanuka bukwi na bukwi kw’umuvuduko wo mu nda bituma imitsi igaburira amara igwira ningoga. Mu masaha 24 gushika ku 72 akurikira, amazi arasohoka mu maraso agasubira mu nda kugira ngo asubire kwuzuza aho hantu, ivyo bikaba bituma amaraso y’umurwayi akora neza mu mitsi y’amaraso agabanuka, ivyo bikaba bitwa Post-Paracentesis Circulatory Dysfunction (PPCD). Amafyigo aravyishura mu kurekura umusemburo mwinshi cane witwa renine, aldosterone be n’umusemburo ugabanya amazi (ADH), ivyo bikaba bituma amaraso agira sodium nke cane (hyponatremie), amafyigo akabura ubushobozi bwo gukora neza (Hepatorenal Syndrome), ascite igasubira vuba, kandi umuntu akagira urupfu rwinshi. Gutera amagarama 6 gushika ku 8 y’amazi 25% IV kuri litiro yose y’amazi akuweho birabuza PPCD.
