A new Infraclavicular Landmark-Based Approach to the Axillary Vein as an Alternative Method of Central Venous Cannulation

2016

Purpose: We developed the new technique of the axillary vein catheterization, which is connected with the determination of only two anatomical points of reference for puncture site identification. The primary outcome of this study was to determine the rate of successful catheterizations and the assessment of procedure success rate, depending on cannulation side as well as physician experience. The secondary objective was to evaluate the early complication rate and to determine whether this method can be used in clinical practice. Methods: The methodology of this prospective, cohort study included catheterization of the axillary vein via the infraclavicular approach. All procedures were perf…

Real-time ultrasound-guided infraclavicular axillary vein cannulation: A prospective study in mechanically ventilated critically ill patients.

2016

Purpose: The main purpose of this study was to define the venipuncture and catheterization success rates and early mechanical complication rates of ultrasound-guided infraclavicular axillary vein cannulation. Materials and methods: We performed in-plane, real-time, ultrasound-guided infraclavicular axillary vein catheterizations under emergency and nonemergency conditions in mechanically ventilated, critically ill patients. Results: We performed 202 cannulation attempts. One hundred and twenty-six procedures (62.4%) were performed under emergency conditions. The puncture of the axillary vein was successful in 98.5% of patients, and the entire procedure success rate was 95.1% (95% confidence…

Percutaneous and surgical treatment of pyogenic liver abscesses: Observation over a 21-year period in 148 patients

2007

Percutaneous drainage of pyogenic liver abscess has become first-line treatment. In the past surgical drainage was preferred in some centres.The aim of this retrospective study was to assess the effectiveness of percutaneous treatments and surgical drainage, in terms of treatment success, hospital stay and costs.Data of 148 patients (90 males; 58 females; mean age, 61 yrs; range, 30-86 yrs) were retrospectively analysed.Patients' outcomes, including the length of hospital stay, procedure-related complications, treatment failure and death, were recorded. Multiple logistic regression model was used for statistical analysis.One hundred and four patients (83 with solitary and 21 with multiple a…

CARDIAC PUNCTURE OF FETUS WITH HURLER'S DISEASE AVOIDING ABORTION OF UNAFFECTED CO-TWIN

Is avoidance of surgery possible in patients with perimenopausal ovarian tumors using transvaginal ultrasound and duplex color Doppler sonography?

1993

A total of 108 cases of small perimenopausal ovarian tumors (largest diameter, less than 7 cm) were evaluated by transvaginal sonography and duplex color Doppler sonography; 101 had criteria for benignity and 7 for malignancy. All cysts were punctured and aspirated to avoid unnecessary surgery (benign cases) and establish the cytologic diagnosis as well as to avoid the risk of leakage (malignant cases). Recurrence rate of benign punctured cysts was 25% within 1 year of follow up. No difference in recurrent rate was seen between pre- and postmenopausal patients (19 of 56 cases in the premenopausal group, and five of 28 cases in the postmenopausal group). The larger the cyst, the greater the …

Dural sac localization using myelography and its application to the lumbosacral epidural in dogs

2020

Background: The techniques described for the identification of the lumbosacral (LS) epidural space in dogs do not guarantee the needle position or an accidental subarachnoid puncture, especially in small size dogs.Aim: To determine the relationship between body weight and the location of the dural sac (DS) using myelography in dogs, and to determine the possibility of subarachnoid puncture during LS epidural based on the position of the DS.Methods: Four masked observers evaluated 70 myelographic studies of dogs, annotating the vertebrae where the DS ended, if it was localized before or after the LS space, and if accidental subarachnoid puncture during LS epidural injection was possible (yes…

Tissue evacuated during joint replacement procedure as a source of mononuclear cells.

2017

Background Different cell populations from bone marrow were used in various clinical trials for cardiac diseases during last decade. Four clinical studies are ongoing in our institution and enroll patients with cardiac diseases, coronary disease, type 2 diabetes, and osteoarthritis. The density gradient is used to separate bone marrow mononuclear cells. Joint replacement procedures were associated with significant loss of tissue. Usually, excess tissue as bone marrow, peripheral blood and fat are removed to clean operation site. The aim of this study is to prove whether removed tissue during joint replacement procedure can be considered as a significant source of mononuclear cells. Methods …

Post laryngectomy speech rehabilitation outcome in elderly patients

2013

The aim of our work has been to evaluate the different options of tracheoesophageal voice rehabilitation in over 70-year-old patients, who had undergone laryngectomy, assessing advantages and drawbacks of this method of vocal recovery. A retrospective study has been carried out. This has included 40 subjects, all aged more than 70 years old, who have been referred to tracheoesophageal voice rehabilitation. It has been realized a phonatory fistula between trachea and esophagus with prosthesis positioning by means of a primary puncture in 18 cases and it has been realized a secondary puncture in 22 cases. The results gathered in these patients were compared with data obtained from a group mad…

Time course of development of transtubular sodium concentration differences in proximal surface tubules of the rat kidney. Micropuncture experiments …

1969

Int the proximal and distal surface tubules isotonic Na reabsorption (Φ Naout) is impaired by adrenalectomy. In the present experiments the time course of development of transtubular Na concentration differences (Na)P−(Na)TF was studied in the proximal convolution. 1. Na concentration was measured in free flow mannitol diuresis. Endproximal (Na)P−(Na)TF averaged 23.0±0.5 meq/l after 8.5±0.6 sec (controls) and 15.2±1.7 meq/l after 13.6±0.5 sec (adrenalectomized rats). 2. In modified stopped flow experiments tubular fluid, aspirated at the beginning of the proximal convolution in mannitol diuresis, was injected between two oil columnes and reaspirated after 28–36 sec of contact time. (Na)P−(N…

Diagnostic procedures in internal medicine. Thoracentesis, paracentesis and arthrocentesis in hospital practice. [Procedure diagnostiche in medicina …

1999

The aim of this paper is to give a rapid and concise guide for the diagnostic procedures frequently used in internist's clinical practice. Thoracentesis, paracentesis and arthrocentesis were analyzed as regards to indications, contraindications, procedure of execution and interpretation of findings. Addressed to the young physician, the present paper could also be useful as a rapid guide for the experienced physician which does not frequently use these procedures.
