Postoperative pulmonary complications and mortality after major abdominal surgery. An observational multicenter prospective study.

BACKGROUND: Postoperative pulmonary complications (PPCs) significantly contribute to postoperative morbidity and mortality. We conducted a study to determine the incidence of PPCs after major elective abdominal surgery and their association with early and 1-year mortality in patient without pre-existing respiratory disease. METHODS: We conducted a multicenter observational prospective clinical study in 40 Italian centers. 1542 patients undergoing elective major abdominal surgery were recruited in a time period of 14 days and clinically managed according to local protocol. The primary outcome was to determine the incidence of PPCs. Further, we aimed to identify independent predictors for PPCs and examine the association between PPCs and mortality. RESULTS: PPCs occurred in 12.6% (95% CI 11.1-14.4%) of patients with significant differences among general (18.3%, 95% CI 15.7-21.0%), gynecological (3.7%, 95% CI 2.1-6.0%) and urological surgery (9.0%, 95% CI 6.0-12.8%). PPCs development was associated with known pre- and intraoperative risk factors. Patients who developed PPCs had longer length of hospital stay, higher risk of 30-days hospital readmission, and increased in-hospital and one-year mortality (OR 3.078, 95% CI 1.825-5.191; P<0.001). CONCLUSIONS: The incidence of PPCs in patients without pre-existing respiratory disease undergoing elective abdominal surgery is high and associated with worse clinical outcome at one year after surgery. General surgery is associated with higher incidence of PPCs and mortality compared to gynecological and urological surgery.

Subcutaneously anchored securement for peripherally inserted central catheters: Immediate, early, and late complications.

BACKGROUND: An adequate stabilization of a vascular device is an important part of insertion bundles and is an effective strategy in reducing complications. Dislodgment has a relevant clinical impact and an increase in healthcare costs. METHOD: We have retrospectively investigated the safety and efficacy of Subcutaneously Anchored Securement (SAS) for Peripherally Inserted Central Catheters (PICC) in cancer patients. RESULTS: We analyzed 639 patients who had a PICC inserted and secured with SAS, over the past 3 years (2018-2020). No immediate complications during SAS placement were reported. In the first 24-48 h, a slight local ecchymosis was reported in 24 cases with rapid spontaneous resolution. No cases of bleeding or hematoma of the exit site were reported. The total number of catheter days was 93078. Dislodgment occurred only in seven cases (1.1%). In 16 patients, the PICC was removed because of catheter-related bloodstream infection (CRBSI): the overall incidence of CRBSI was 0.17 per 1000 catheter days. Symptomatic venous thrombosis was documented in 12 patients (1.9%) and treated with low molecular weight heparin without PICC removal. We had no cases of irreversible lumen occlusion. In 17 patients, local discomfort-including device-related pressure ulcers and painful inflammation-was reported: these cases were treated without SAS removal or PICC removal. CONCLUSION: In this retrospective analysis, subcutaneously anchored securement of PICCs was a safe and effective strategy for reducing the risk of dislodgment.

Taurolidine lock in the treatment of colonization and infection of totally implanted venous access devices in cancer patients.

BACKGROUND: Taurolidine lock is known to be effective in preventing catheter-related infections in a variety of venous access devices, including long term venous access devices for chemotherapy. Though, literature about the use of taurolidine for treating catheter colonization or catheter-related blood stream infection is scarce. METHOD: We have retrospectively reviewed the safety and efficacy of 2% taurolidine lock for treatment of catheter-colonization and of catheter-related bloodstream infection in cancer patients with totally implanted venous access devices. Diagnosis of colonization or catheter-related infection was based on paired peripheral and central blood cultures, according to the method of Delayed Time to Positivity. RESULTS: We recorded 24 cases of catheter-related infection and two cases of colonization. Taurolidine lock-associated with systemic antibiotic therapy-was successful in treating all cases of catheter-related infection, with disappearance of clinical symptoms, normalization of laboratory values, and eventually negative blood cultures. Taurolidine lock was also safe and effective in treating device colonization. No adverse effect was reported. CONCLUSION: In our retrospective analysis, 2% taurolidine lock was completely safe and highly effective in the treatment of both catheter-colonization and catheter-related bloodstream infection in cancer patients with totally implanted venous access devices.

A multicenter retrospective study on 4480 implanted PICC-ports: A GAVeCeLT project.

BACKGROUND: PICC-ports may be defined as totally implantable central venous devices inserted in the upper limb using the current state-of-the-art techniques of PICC insertion (ultrasound-guided venipuncture of deep veins of the arm, micro-puncture kits, proper location of the tip preferably by intracavitary ECG), with placement of the reservoir at the middle third of the arm. A previous report on breast cancer patients demonstrated the safety and efficacy of these devices, with a very low failure rate. METHODS: This retrospective multicenter cohort study-developed by GAVeCeLT (the Italian Group of Long-Term Venous Access Devices)-investigated the outcomes of PICC-ports in a large cohort of unselected patients. The study included 4480 adult patients who underwent PICC-port insertion in five Italian centers, during a period of 60 months. The primary outcome was device failure, defined as any serious adverse event (SAE) requiring removal. The secondary outcome was the incidence of temporary adverse events (TAE) not requiring removal. RESULTS: The median follow-up was 15.5 months. Device failure occurred in 52 cases (1.2%), the main causes being local infection (n = 7; 0.16%) and CRBSI (n = 19; 0.42%). Symptomatic catheter-related thrombosis occurred in 93 cases (2.1%), but removal was required only in one case (0.02%). Early/immediate and late TAE occurred in 904 cases (20.2%) and in 176 cases (3.9%), respectively. CONCLUSIONS: PICC-ports are safe venous access devices that should be considered as an alternative option to traditional arm-ports and chest-ports when planning chemotherapy or other long-term intermittent intravenous treatments.

Preprocedural ultrasound vascular assessment is essential to decision-making.

Reliable venous access should be part of the clinical-therapeutic path of all cancer patients. A correct preliminary ultrasound evaluation of the patient's veins and the choice of the suitable vein are the fundamental requirements to guarantee a stable and long-lasting venous access.

A novel ultrasound-guided approach to the axillary vein: Oblique-axis view combined with in-plane puncture.

INTRODUCTION: Ultrasound-guided cannulation of the axillary vein in the infraclavicular area has several potential advantages for both short-term and long-term venous access devices. Currently, there are two techniques to approach axillary vein for ultrasound-guided cannulation: out-of-plane puncture in the short-axis view and the in-plane puncture in the long-axis view. We propose a novel ultrasound-guided puncture technique of axillary vein for centrally inserted central catheter placement, which consists in the oblique-axis view of the axillary vein coupled with the in-plane puncture. The main objectives of this study were feasibility and safety of this approach. The primary endpoints were the success rate and early complications; the secondary endpoints were late complications. METHODS: We analyzed data from a retrospective cohort of 80 ultrasound-guided cannulation of axillary vein performed with the oblique axis-in-plane technique in 80 cancer patients requiring a totally implantable central venous access, at CRO Aviano National Cancer Institute, during the period from January 2016 up to October 2017. We focused on the percentage of successful venous cannulation at the first attempt and on the cumulative incidence of early and late complications. RESULTS: Axillary vein cannulation was successful at the first attempt in 77 out of 80 patients (96%). We had no significant complications during placement or in the first 48 h. The total number of catheter days was 27,432. The cumulative incidence of catheter-related bloodstream infection was of 0.036 per 1000 catheter days (only one case). We had no infection of the pocket of the reservoir, no symptomatic venous thrombosis, and no catheter migration. CONCLUSION: Our data show that the oblique axis-in-plane technique of the ultrasound approach to the axillary vein is feasible and safe.

The postoperative analgesic efficacy of preperitoneal continuous wound infusion compared to epidural continuous infusion with local anesthetics after colorectal cancer surgery: a randomized controlled multicenter study.

BACKGROUND: Open colorectal cancer (CRC) surgery induces severe and prolonged postoperative pain. The optimal method of postoperative analgesia in CRC surgery has not been established. We evaluated the efficacy of preperitoneal continuous wound infusion (CWI) of ropivacaine for postoperative analgesia after open CRC surgery in a multicenter randomized controlled trial. METHODS: Candidates for open CRC surgery randomly received preperitoneal CWI analgesia or continuous epidural infusion (CEI) analgesia with ropivacaine 0.2% 10 mL/h for 48 hours after surgery. Fifty-three patients were allocated to each group. All patients received patient-controlled IV morphine analgesia. RESULTS: Over the 72-hour period after the end of surgery, CWI analgesia was not inferior to CEI analgesia. The difference of the mean visual analog scale score between CEI and CWI patients was 1.89 (97.5% confidence interval = -0.42, 4.19) at rest and 2.76 (97.5% confidence interval = -2.28, 7.80) after coughing. Secondary end points, morphine consumption and rescue analgesia, did not differ between groups. Time to first flatus was 3.06 ± 0.77 days in the CWI group and 3.61 ± 1.41 days in the CEI group (P = 0.002). Time to first stool was shorter in the CWI than the CEI group (4.49 ± 0.99 vs 5.29 ± 1.62 days; P = 0.001). Mean time to hospital discharge was shorter in the CWI group than in the CEI group (7.4 ± 0.41 and 8.0 ± 0.38 days, respectively). More patients in the CWI group reported excellent quality of postoperative pain control (45.3% vs 7.6%). Quality of night sleep was better with CWI analgesia, particularly at the postoperative 72-hour evaluation (P = 0.009). Postoperative nausea and vomiting was significantly less frequent with CWI analgesia at 24 hours (P = 0.02), 48 hours (P = 0.01), and 72 hours (P = 0.007) after surgery evaluations. CONCLUSIONS: Preperitoneal CWI analgesia with ropivacaine 0.2% continuous infusion at 10 mL/h during 48 hours after open CRC surgery provided effective postoperative pain relief not inferior to CEI analgesia.

Supportive therapy of elderly cancer patients.

Elderly cancer patients often require supportive care due to the physiologic decline of organs and apparatus linked with the aging process per se, and for the effects of tumor or of anticancer treatments. Pain and nutritional deficits are some clinical aspects requiring supportive care. Lack of studies on these latter topics does not allow an in depth analysis of the problem. The present review deals with literature concerning pain and nutritional problems in the general cancer population with emphasis on aspects typical for elderly cancer subjects. Physiologic and cancer-related changes in body composition, physical function and cognitive capacity of the elderly are presented and, when appropriate, linked with pathogenetic factors of pain and malnutrition, as well as their treatment. Pain demographic data, pain intensity evaluation and currently available techniques to provide pain relief such as etiologic treatment, analgesic pharmacotherapy and invasive analgesic procedures, are extensively discussed. Causes and assessment of malnutrition as well as available nutritional approaches such as oral, enteral and parenteral nutrition are also debated.
