PURPOSE: To describe a technique of vitreous base visualisation through trans-scleral illumination using a standard 25-gauge light probe. METHODS: All vitrectomies are performed using 25-gauge+ instruments and valved trocars. A non-contact viewing system is used to visualise the retina. After core vitrectomy and the necessary additional procedures, triamcinolone acetonide (Kenacort) is injected in the vitreous cavity. Then, the standard 25-gauge light pipe is covered with a sleeve obtained from a 20-gauge venflon cannula...

BACKGROUND: The analysis of angiogenesis factors in the blood of tumor patients has given diverse results on their prognostic or predictive value. Since mediators of angiogenesis are stored in platelets, their measurement in plasma is sensitive to inadvertent platelet activation during blood processing. METHODS: Variants of blood withdrawal and plasma preparation were evaluated by ELISA for the detection of TSP-1, PF-4, VEGF and PD-ECGF. A total of 22 pancreatic cancer patients and 29 healthy volunteers were evaluated...

Peripheral veins have been used successfully for patients requiring short- to medium-term total parenteral nutrition. This study prospectively compares two methods of peripheral parenteral nutrition (PPN). Forty-six patients requiring parenteral nutrition (PN) were identified prospectively. Fifty courses of PPN were prescribed using a standardized PPN formula of 9.3 g nitrogen, 1400 kCal, 2500 ml (KABI II, Pharmacia). Patients were randomized to receive PPN via 23G, 15 cm flexane catheters (Nutriline) inserted into an antecubital vein which remained in-situ with a continuous infusion over 24 h, or to receive 12-h cyclical infusions through peripherally sited 18G catheters (Venflon) which were removed postinfusion and reinserted into the contralateral forearm on alternate days...

BACKGROUND: Breast abscesses have usually been treated by incision and drainage. During the past 10 years conservative treatment with repeated ultrasound-guided drainage to evacuate the abscess combined with antibiotic treatment has become a valuable alternative. PATIENTS AND METHODS: From 1991 to 2003 the authors treated 17 patients with puerperal abscess with this method. Under local anesthesia with ultrasound guidance a thick needle (preferably a Venflon) is introduced into the cavity...

Pain related to the insertion of intravenous catheters is a major issue for many patients. This study investigated differences in pain on insertion for three different catheters - Optiva 1, Biovalve and Venflon 2 - as assessed by 100 volunteers. Clinicians also assessed a variety of parameters related to their overall ease of use. This study demonstrates that Optiva 2 can offer significant benefits for both patient and clinician. Pain on insertion was significantly lower with Optiva 2 than with Venflon 2, but comparable with Biovalve...

A simple technique is described that facilitates a proper procedure of venous end-to-end anastomosis during neurosurgical procedures. This technique, which consists of insertion of a Venflon tube in the vein during anastomosis, results in easier handling and proper apposition of the vein, resulting in an improved quality of the anastomosis. The technique was successfully applied in a patient after parasagittal meningioma resection, and the patency of the cortical vein was confirmed postoperatively on magnetic resonance venography...

One way of saving junior doctors' time and patients' pain is to take blood samples through a venflon immediately after its insertion. This is not, however, universal practise as some believe the results, especially urea and electrolytes, are unreliable. We have surveyed junior doctors in our hospital about this practise and prospectively compared venflon and vein blood samples.

In order to study the influence of portal lipid loading on the extraction rate of bile salts by the liver, four cholecystectomized calves (mean body weight 103 kg) were fitted with permanent cannulae to the common bile duct, duodenum and portal vein. A venflon catheter was also set up in the jugular vein to collect blood for analysis of fatty acids (FA) and bile salts (PBS) in plasma. The experiments were divided into two parts. In the first part sodium taurocholate (TCHNa) was infused for at least 2 h at a rate of 25 mumol/min into the duodenum to stabilize the bile flow and bile salt output in bile and the concentration in plasma...

In 30 patients subjected to craniotomy, subdural pressure was measured with a 22G/0.8 mm Venflon cannula connected to a pressure transducer system. The measurements were performed after removal of the bone flap and just before opening of the dura. The subdural pressure was correlated with the tactile estimation of dural tension and the tendency to brain herniation after opening the dura. The results indicate that generally there is a poor agreement between the tactile feeling of dural tension and subdural pressure...

A comparison was made of the three 22-gauge ported intravenous cannulae available in New Zealand--Venflon 2, Vasofix Braunule and Insyte. All cannulae performed satisfactorily in terms of overall success of cannulation although significant differences were apparent in both clinical and laboratory performance. Anaesthetists' clinical preference was for Insyte and Venflon 2 brands, perceiving these to have greater ease of handling and better packaging. In a series of laboratory studies, Vasofix was found to have the highest flowrate, the fastest time to flashback and the lowest valve opening pressure...

Two hundred and seventy-eight patients scheduled for all types of surgery and premedicated with diazepam and metoclopramide were randomly allocated to one of four groups to compare the relative pain of an injection of 0.25 ml of lignocaine 1% via a 25 gauge needle with the pain of the siting of a 21 gauge Butterfly (Abbott), 23 gauge Butterfly or a 20 gauge Venflon (Vigo Spectramed). The injection of lignocaine and insertion of the 23 gauge Butterfly were associated with the least complaints of pain and least observed responses to pain...

Three commonly available local anaesthetics were compared, in a controlled trial, for use before venous cannulation. The pain of application of the local anaesthetic, the pain of cannulation, and the rate of successful cannulations were compared. The value of EMLA cream applied for 5 min was questioned. Venous cannulation with a 20G venflon was found to be significantly more painful than the application of any of the local anaesthetics (P < 0.01). Lignocaine 1%, injected subcutaneously, and ethyl chloride spray significantly reduced the pain of venous cannulation (P < 0...

Twelve patients with cystic fibrosis received 12 courses of intravenous antibiotics, each over 10-14 days, both with and without the use of an extended-life disposable filter. The design of the trial was to replace the Venflon cannulae as they became non-patent and inserting a filter on alternate occasions. Thus each patient acted as her/his own control. Comparison of times during which cannulae remained patent showed a 50% improvement with use of a filter for 4 patients and no change for 7 patients. There was no significant difference associated with the use of a filter for the group as a whole but our small sample size excludes modest improvements...

The possibility of a brachial plexus block in children is discussed and presented as a relatively safer method than general anaesthesia. 10 cases aged between 4 and 13 years are reported. Intensive verbal communication with the child during the procedure is essential and sedation may have disadvantages. Prolonged post-operative pain prevention can be achieved by in an indwelling Venflon cannula.
