A Tunneled Catheter Placement Program for Community Hospices.

CONTEXT: The symptoms associated with the excessive fluid accumulation of ascites or pleural effusions can be intractable to medical management and can have a significant negative impact on quality of life of hospice patients. Hospice of the Valley, a community-based, nonprofit hospice agency has historically referred patients to outpatient providers for paracentesis, thoracentesis, and placement of tunneled drainage catheters. OBJECTIVES: To describe an in-house pilot program of tunneled catheter placement to provide immediate and longer-term symptom relief for selected hospice patients. METHODS: The logistics and cost of the pilot program are described. Key data elements, including select demographics, patient eligibility screening, and incidence of procedure-related or late complications are reported. RESULTS: A total of 135 drainage procedures completed on 127 unique hospice patients over 27 months (2020-2023) were reviewed. The rate of procedure-related complications (<4%) and late complications (<3%) are low. The average cost per procedure ($1030) compares favorably with outpatient providers' fees. The program was well-accepted by the interdisciplinary hospice team, patients, and families. CONCLUSIONS: An in-house program of tunneled catheter placement is a feasible option for hospice providers with low-cost exposure and high potential for improved quality of life and symptom relief for selected patients.

Continuous passive paracentesis versus large-volume paracentesis in the prevention and treatment of intra-abdominal hypertension in the critically ill cirrhotic patient with ascites (COPPTRIAHL): study protocol for a randomized controlled trial.

BACKGROUND: Critically ill patients with cirrhosis and ascites are at high risk for intra-abdominal hypertension (IAH) which increases mortality. Clinical guidelines recommend maintaining intra-abdominal pressure (IAP) below 16 mmHg; nonetheless, more than three quarters of critically ill patients with cirrhosis develop IAH during their first week of ICU stay. Standard-of-care intermittent large-volume paracentesis (LVP) relieves abdominal wall tension, reduces IAP, optimizes abdominal perfusion pressure, and is associated with short-term improvement in renal and pulmonary dysfunction. However, there is no evidence of the superiority of different paracentesis strategies in the prevention and treatment of IAH in critically ill patients with cirrhosis. This trial aims to compare the outcomes of continuous passive paracentesis versus LVP in the prevention and treatment of IAH in patients with cirrhosis and ascites. METHODS: An investigator-initiated, open label, randomized controlled trial, set in a general ICU specialized in liver disease, was initiated in August 2022, with an expected duration of 36 months. Seventy patients with cirrhosis and ascites will be randomly assigned, in a 1:1 ratio, to receive one of two methods of therapeutic paracentesis. A stratified randomization method, with maximum creatinine and IAP values as strata, will homogenize patient baseline characteristics before trial group allocation, within 24 h of admission. In the control group, LVP will be performed intermittently according to clinical practice, with a maximum duration of 8 h, while, in the intervention group, continuous passive paracentesis will drain ascitic fluid for up to 7 days. The primary endpoint is serum creatinine concentration, and secondary endpoints include IAP, measured creatinine clearance, daily urine output, stage 3 acute kidney injury and multiorgan dysfunction assessed at day 7 after enrollment, as well as 28-day mortality rate and renal replacement therapy-free days, and length-of-stay. Prespecified values will be used in case of renal replacement therapy or, beforehand ICU discharge, liver transplant and death. Safety analysis will include paracentesis-related complication rate and harm. Data will be analyzed with an intention-to-treat approach. DISCUSSION: This is the first trial to compare the impact of different therapeutic paracentesis strategies on organ dysfunction and outcomes in the prevention and treatment of IAH in critically ill patients with cirrhosis and ascites. TRIAL REGISTRATION: ClinicalTrials.gov NCT04322201 . Registered on 20 December 2019.

Large Volume Paracentesis in Patients with Liver Cirrhosis Temporarily Diminishes Blood Cell Count.

Background: Large-volume paracentesis is the preferred treatment for patients with severe and refractory ascites. Several complications were reported during therapeutical paracentesis. However, there are very few published studies on the change in blood cell count after paracentesis. This study aimed to evaluate any changes in blood cell counts after ascites fluid drainage. Methods: This study was conducted on patients with severe ascites and chronic liver disease who underwent large-volume paracentesis at Namazi Hospital, in Shiraz, Iran, between March 2021 and February 2022. A data gathering form containing the patient's medical history, cause of cirrhosis, ascites fluid volume, as well as routine tests including primarily sodium, potassium, and basal creatinine, was filled out. Before and after the surgery, the total blood cell count was measured. Before the procedure, adjustment was made in the case of coagulopathy and albumin deficiency. The effect of factors such as the volume of drained fluid, splenomegaly, antibiotics, and steroid use was assessed on the changes in the number of blood cells. Using the JAMOVI 2.3.9 software, a paired t test and multiple regression were applied for statistical analysis (P<0.001). Results: The study included 37 patients. After the paracentesis procedure, the number of blood cells significantly decreased in all groups (P<0.001). The followings are the amounts of each type of blood cells before and after the procedure: Platelet=153837±91862 and 115648±69136, red blood cells=3.53±0.784 and 3.22±0.705, white blood cells=12.3±7.78 and 8.6±5.5. None of the study variables, including drained volume, splenomegaly, antibiotics, and steroid use, were significant predictors of the changes in the blood cell count after paracentesis (P>0.001). Conclusion: The findings of the present study showed that children with tense ascites who had large-volume paracentesis might experience a sharp drop in blood cell count after the procedure, which was a transient physiological condition.

[Current status of the method of collecting aqueous humor by anterior chamber paracentesis].

Anterior chamber paracentesis (ACP) is a commonly used ophthalmic technique with broad clinical applications. It plays an important role in the diagnosis of intraocular infections, vitreoretinal lymphoma, and other diseases. However, the current ACP methods used in clinical practice have some issues and potential risks. There is no unified standard for the procedural steps, environment, and perioperative management. Therefore, this article provides a systematic review of various methods and devices for ACP and briefly summarizes the current clinical ACP environment, perioperative management, and safety considerations. The aim of this review is to provide insights into the current status and future prospects of ACP, with the goal of optimizing the safety and efficacy of this technique.

Is Low Volume Drainage of Ascites Associated With Improved Survival in Digestive System Cancer Patients With Malignant Ascites?-A Retrospective Cohort Study.

Objectives: To determine whether the volume of paracentesis for malignant ascites in acute care hospital wards is associated with survival and symptom relief. Methods: Patients with malignant ascites caused by digestive system cancer who underwent paracentesis between January 2010 and April 2022 were retrospectively analyzed from medical records. Collected data included the drainage volume per paracentesis procedure, survival time from the first paracentesis procedure, symptoms, and adverse events. According to the volume per paracentesis procedure, we divided the patients into the "small-drainage" (≤1500 mL) and "standard-drainage" (>1500 mL) groups. Results: The median age of the 144 patients was 69 years, 33% were female, and 64% had gastrointestinal cancer. The median survival from the first paracentesis procedure was 36 days. Eighty-nine (61.8%) and 55 (38.2%) patients were allocated to the small-drainage and standard-drainage groups, respectively. The median number of paracentesis procedures in the small-drainage and standard-drainage groups was 12 and 7, respectively (P=.001). The median survival in the small-drainage and standard-drainage groups was 50 and 44 days, respectively (P=.76). The multivariate analysis showed that the amount of drainage per session was not significantly associated with survival. Symptoms improved similarly in the 2 groups. No serious adverse events were observed. Conclusions: Paracentesis was demonstrated to be effective and safe, irrespective of the amount of fluid drained, for patients with malignant ascites in an acute care hospital. Thus, a strategy of limiting the amount of drainage is not associated with longer survival.

Randomized crossover trial of 'Roll-over' technique of abdominal paracentesis versus standard technique in suspected malignant ascites.

BACKGROUND: The sensitivity of single abdominal paracentesis for diagnosis of peritoneal carcinomatosis (PC) varies from 40-70%. We hypothesized that rolling-over the patient before paracentesis might improve the cytological yield. RESEARCH DESIGN AND METHODS: This was a single center pilot study with a randomized cross-over design. We compared the cytological yield of fluid obtained by roll-over technique (ROG) with standard paracentesis (SPG) in suspected PC. In the ROG group, patients were rolled side-to-side thrice, and the paracentesis was done within 1 minute. Each patient served as their own control, and the outcome assessor (cytopathologist) was blinded. The primary objective was to compare the tumor cell positivity between SPG and ROG groups. RESULTS: Of 71 patients, 62 were analyzed. Of 53 patients with malignancy-related ascites, 39 had PC. Most of the tumor cells were adenocarcinoma (30, 94%) with one patient each having suspicious cytology and one having lymphoma. The sensitivity for diagnosis of PC was (31/39) 79.49% in SPG group and (32/39) 82.05% in ROG group (p = 1.00). The cellularity was similar between both the groups (good cellularity in 58% of SPG and 60% of ROG, p = 1.00). CONCLUSIONS: Rollover paracentesis did not improve the cytological yield of abdominal paracentesis. TRIAL REGISTRATION: CTRI/2020/06/025887 and NCT04232384.

Human Albumin Infusion for the Management of Liver Cirrhosis and Its Complications: An Overview of Major Findings from Meta-analyses.

INTRODUCTION: The role of human albumin (HA) infusion in cirrhotic patients has been increasingly recognized. This paper aims to summarize the evidence from meta-analyses regarding HA infusion for the management of cirrhosis and its complications. METHODS: A systematic search in the PubMed, EMBASE, and Cochrane library databases, and in reference lists was conducted. All relevant meta-analyses were identified and their findings were reviewed. The Assessment of Multiple Systematic Reviews 2 (AMSTAR-2) checklist was used to evaluate the methodological quality and the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) system to assess the quality of evidence for significant outcomes. RESULTS: Among 300 papers initially identified, 18 meta-analyses have been included. Short- and long-term HA infusion at high doses decreased the mortality of patients with decompensated cirrhosis. In cirrhotic patients with ascites, long-term HA infusion reduced the recurrence of ascites, but not mortality. In cirrhotic patients undergoing large-volume paracentesis (LVP), HA infusion reduced the incidence of post-paracentesis circulatory dysfunction and hyponatremia, but not mortality or renal impairment. In cirrhotic patients with overt hepatic encephalopathy (HE), HA infusion improved the severity of overt HE, but not overall mortality. In cirrhotic patients with spontaneous bacterial peritonitis (SBP), but not those with non-SBP infections, HA infusion reduced the mortality and renal impairment. In cirrhotic patients with type-1 hepatorenal syndrome (HRS), an increment of 100 g in cumulative HA dose increased 1.15-fold survival, but not HRS reversal. In these meta-analyses, the quality of methodology was low or critically low, and that of the evidence was from very low to moderate. CONCLUSIONS: Based on the limited evidence from these meta-analyses, HA infusion appears to be beneficial in cirrhotic patients with ascites, overt HE, and SBP and in those undergoing LVP, but not in those with non-SBP infections.

Paracentesis: Faster and easier using the RenovaRP® pump.

PURPOSE Paracentesis is commonly performed in interventional radiology practice, and large volume paracentesis (LVP) using wall suction can take up to an hour to complete, placing significant stress on room and resource time. As the number of LVP procedures performed by Interventional Radiologists continue to increase, this study was undertaken to analyze the impact of the RenovaRP® Paracentesis Management System (GI Supply) on procedure time and patient satisfaction. METHODS Between March 9, 2020 and May 29, 2020, procedural data and patient satisfaction was collected as part of a practice quality improvement project and retrospectively analyzed on 39 sequential paracenteses performed with wall suction prior to acquiring the RenovaRP® system and subsequently on 42 paracenteses performed with use of the device. RESULTS A substantially higher fluid flow rate was found using the RenovaRP® system compared to wall suction, 237.2 mL/min vs. 108.6 mL/min (P < .001). This resulted in a significant decrease in procedure room time from 53 min to 31 min (P < .001). There was associated improvement in the patient experience during paracentesis. CONCLUSION The RenovaRP® decreases procedure time for LVP with improvement in the patient experience during paracentesis.

[Ultrasound-guided paracentesis: technical, diagnostic and therapeutic aspects for the modern nefrologist].

Ascites is a pathological accumulation of fluid in the peritoneal cavity due to various etiologies, often associated with renal failure. Paracentesis is a simple method of removing ascitic fluid by inserting a needle into the peritoneal cavity, often performed at the patient's bedside. It can be both diagnostic and therapeutic. Ultrasound imaging allows the diagnosis of ascites, the identification of the puncture site on the abdominal wall during the pre-procedural phase, the real time evaluation of the needle and the continuous course of the maneuver. This eco-guide technique has higher effectiveness and lower risk of complications than the "blind" venipuncture technique. Ultrasound-guided paracentesis, when performed by nephrologists, reduces the waiting time both for the execution of paracentesis and for the diagnosis, treatment and follow-up of ascites.

3D-Slicer Software-Assisted Neuroendoscopic Surgery in the Treatment of Hypertensive Cerebral Hemorrhage.

OBJECTIVE: To explore the 3D-slicer software-assisted endoscopic treatment for patients with hypertensive cerebral hemorrhage. METHODS: A total of 120 patients with hypertensive cerebral hemorrhage were selected and randomly divided into control group and 3D-slicer group with 60 cases each. Patients in the control group underwent traditional imaging positioning craniotomy, and patients in the 3D-slicer group underwent 3D-slicer followed by precision puncture treatment. In this paper, we evaluate the hematoma clearance rate, nerve function, ability of daily living, complication rate, and prognosis. RESULTS: The 3D-slicer group is better than the control group in various indicators. Compared with the control group, the 3D-slicer group has lower complications, slightly higher hematoma clearance rate, and better recovery of nerve function and daily living ability before and after surgery. The incidence of poor prognosis is low. CONCLUSION: The 3D-slicer software-assisted endoscopic treatment for patients with hypertensive intracerebral hemorrhage has a better hematoma clearance effect, which is beneficial to the patient's early recovery and reduces the damage to the brain nerve of the patient.

Factors predicting hip joint aspiration yield or "dry taps" in patients with total hip arthroplasty.

BACKGROUND: Image-guided joint aspirations used to assist the diagnosis of periprosthetic joint infection (PJI) may commonly result in a dry tap-or insufficient fluid for culture and cell count analysis. Dry tap aspirations are painful and invasive for patients and often utilize a subsequent saline lavage to obtain a microbiology sample. Currently, there is a paucity of the literature addressing predictors that could suggest whether a dry tap will occur. The purpose of this study was to examine the effects of various factors on "dry tap" occurrence in patients with suspected PJI following total hip arthroplasty (THA). METHODS: A retrospective review was performed among THA patients suspected for PJI who received image-guided joint aspiration procedures at our institution from May 2016 to February 2020. The procedural factors included the imaging modality used for aspiration, anatomic approach, needle gauge size used, and the presence of a trainee. The patient-specific factors included number of prior ipsilateral hip surgeries, femoral head size, ESR/CRP values, and BMI. RESULTS: In total, 336 patients met our inclusion criteria. One hundred and twenty hip aspirations resulted in a dry tap (35.7%) where the patients underwent a saline lavage. Among the procedural and patient-specific factors, none of the factors were found to be statistically different between the two cohorts nor conferred any greater odds of a dry tap occurring. CONCLUSION: No associations with dry tap occurrence were found among the procedural and patient-specific factors studied. Further research is needed to identify additional factors that may be more predictive of dry taps.

AL Lambda Amyloidosis Activates Acute Liver Failure in the Absence of Plasma Cell Dyscrasia.

A patient with systemic amyloidosis developed portal hypertension, acute liver failure and multiorgan dysfunction. Extensive testing was unrevealing for paraproteinemia, plasma cell dyscrasia, infectious, or inflammatory conditions. He was transferred to our institution for orthotopic liver transplant evaluation but was ultimately declined given clinical instability and dysautonomia. Post-mortem evaluation revealed extensive amyloid deposition in multiple organs determined to be AL-lambda amyloidosis.

Efficacy of needle aspiration in patients with oral-maxillofacial abscesses: A retrospective study of 15 consecutive patients.

The aim of this study was to determine the adequacy and safety of needle aspiration (NA) as an alternative to open surgical drainage for oral-maxillofacial abscesses. Fifteen consecutive patients who were diagnosed with oral-maxillofacial abscesses via contrast-enhanced CT from January 2020 to December 2020 were included. All patients were on antibiotics and treated with NA under local anaesthesia using a 20 mL syringe. Data collection included patient characteristics, signs and symptoms, physical examinations, laboratory tests, imaging findings, and outcomes. Next-generation sequencing (NGS) was used to identify the infectious microorganisms from the abscess samples. The study included 15 patients with oral-maxillofacial abscesses. None of our 15 patients required surgical incision and drainage, although repeat aspiration was required. However, after the first NA, the pain was reportedly extremely relieved for all patients. The average duration of antibiotic treatment was 9.20 ± 5.15 days (range 4-23 days). The abscess-affected spaces mainly included the masseter space and submandibular space. Odontogenic infection was the most common aetiology in 15 patients (10/15). The average volume of the abscesses on CT was 5866.26 ± 3627.18 mm3. The main pathogens identified in this study were Prevotella oris (5/15), Peptostreptococcus stomatis (4/15) and Porphyromonas endodontalis (2/15). According to the results of our study, the data support the use of NA as an effective, minimally invasive treatment modality for oral-maxillofacial abscesses. Surgeons should familiarise themselves with this technique, as it can easily be performed in the clinic using local anaesthesia, culture samples may be obtained, and airway obstruction and pain may be relieved.

Effectiveness of Hematoma Aspiration and Platelet-rich Plasma Muscle Injections for the Treatment of Hamstring Strains in Athletes.

INTRODUCTION: The effect of platelet-rich plasma (PRP) treatment on recovery in acute hamstring injuries is controversial. Previous study results are inconsistent, and a standardized therapeutic approach has not been established yet. PURPOSE: To assess the treatment effect using a combination of hematoma aspiration and muscle strain PRP injection in partial hamstring muscle tears (grade 2 strains) in athletes. METHODS: Magnetic resonance imaging of athletes with grade 2 hamstring strains were reviewed from 2013 to 2018. From 2013 to 2015, athletes were treated conservatively, and from 2016 to 2018, with a combination of ultrasound-guided hematoma aspiration and PRP muscle strain injection. The outcome, including return-to-play (in days) and recurrence rate, was compared retrospectively between both groups (conservative vs aspiration/PRP) using ANOVA and Fisher's exact test. There was no significant difference in age, type of sport, and muscle involvement (including injury grade/location, hamstring muscle type, and length/cross-sectional area of the strain). RESULTS: Fifty-five athletes (28 treated conservatively, 27 with hematoma aspiration/PRP injection) were included. Average return-to-play time (mean) was 32.4 d in the conservative group and 23.5 d in the aspiration/PRP group (P < 0.001). Recurrence rate of the hamstring strain was 28.6% (8/28) in the conservative treatment group and less than 4% (1/27) in the aspiration/PRP group (P = 0.025). CONCLUSIONS: Athletes with grade 2 hamstring strains treated with a combination of hematoma aspiration and PRP injection had a significantly shorter return-to-play and a lower recurrence rate compared with athletes receiving conservative treatment.

Pneumatic retinopexy as a treatment for rhegmatogenous retinal detachment in pediatric patients meeting PIVOT criteria.

OBJECTIVE: To report the results of pneumatic retinopexy (PnR) as the initial treatment in pediatric patients with rhegmatogenous retinal detachment (RRD) fulfilling The Pneumatic Retinopexy versus Vitrectomy for the Management of Primary Rhegmatogenous Retinal Detachment Outcomes Randomized Trial (PIVOT) criteria. DESIGN: A retrospective multicentre study. PARTICIPANTS: Pediatric patients who underwent outpatient PnR as the initial treatment for RRD from January 2006 to July 2019 who met PIVOT criteria. METHODS: Patients underwent anterior chamber paracentesis followed by intravitreal injection of sulfur hexafluoride (SF6) gas. Either laser retinopexy was performed following retinal reattachment or cryopexy was performed at the time of the initial procedure. RESULTS: A total of 20 eyes of 20 consecutive patients met inclusion criteria and were included in this study. Mean (± standard deviation [SD]) follow-up time was 42.2 ± 38.0 months. Mean patient age was 14.4 years (range, 9-18). There were 17 males and 3 females. The mean (± SD) logMar visual acuity improved from 0.73 ± 0.82 (Snellen equivalent approximately 20/100) to 0.37 ± 0.46 (Snellen equivalent approximately 20/50; p = 0.02) at 3 months and to 0.40 ± 0.54 (Snellen equivalent approximately 20/50; p = 0.05) at last follow-up. Primary reattachment rate was 85% (17/20) at 3 months and 75% (15/20) at last follow-up visit. CONCLUSIONS: PnR may be an effective treatment option for RRD in pediatric patients meeting PIVOT criteria.

Does Point-of-Care Ultrasound Change the Needle Insertion Location During Routine Bedside Paracentesis?

BACKGROUND: Paracentesis is a bedside procedure to obtain ascitic fluid from the peritoneum. Point-of-care ultrasound (POCUS) improves the safety of some medical procedures. However, the evidence supporting its utility in paracentesis is limited. OBJECTIVE: We aimed to assess if POCUS would yield a user-preferred site for needle insertion compared to conventional landmarking, defined as a ≥ 5 cm change in location. DESIGN: This was a prospective non-randomized trial comparing a POCUS-guided site to the conventional anatomic site in the same patient. PARTICIPANTS: Adult patients at Kingston Health Sciences Centre undergoing paracentesis were included. INTERVENTIONS: Physicians landmarked using conventional technique and compared this to a POCUS-guided site. The paracentesis was performed at whatever site was deemed optimal, if safe to do so. MAIN MEASURES: Data collected included the distance from the two sites, depth of fluid pockets, and anatomic considerations. KEY RESULTS: Forty-five procedures were performed among 30 patients and by 24 physicians, who were primarily in their PGY 1 and 2 years of training (33% and 31% respectively). Patients' ascites was mostly due to cirrhosis (84%) predominantly due to alcohol (47%) and NAFLD (34%). Users preferred the POCUS-guided site which resulted in a change in needle insertion ≥ 5 cm from the conventional anatomic site in 69% of cases. The average depth of fluid was greater at the POCUS site vs. the anatomic site (5.4±2.8 cm vs. 3.0±2.5 cm, p < 0.005). POCUS deflected the needle insertion site superiorly and laterally to the anatomic site. The POCUS site was chosen (1) to avoid adjacent organs, (2) to optimize the fluid pocket, and (3) due to abdominal wall considerations, such as pannus. Six cases landmarked anatomically were aborted when POCUS revealed inadequate ascites. CONCLUSIONS: POCUS changes the needle insertion site from the conventional anatomic site for most procedures, due to optimizing the fluid pocket and safety concerns, and helped avoid cases where an unsafe volume of ascites was present.
