The purpose of this study was to determine the effectiveness of pneumatic reduction of intussusception using equipment readily available in the hospital. Twenty-two children aged between four months and four years had pneumatic reduction of intussusception. The device used was assembled using (i) a hand-held pump attached to a pressure gauge, and (ii) a 3-way Foley's balloon catheter. There was a 73% success rate and there were no complications. The device used was effective and safe for the pneumatic reduction of intussusception.
Intravenous (IV) infusion of medical fluid is a very common procedure used as part of medical procedure treatment. It is also the best alternative medical administration route when medical administration through orally is impossible. The most common use of VAD is the short Peripheral IV Catheter (PIVC) or recognized as IV Cannula. In spite of that, even with experience used of PIVC in medical practice nowadays the rate of IV access failure is very high which is up to 69%. Intensive research studies shows the dislodgement case is one of the major contributions of PIVC failure. For some reason only a fewer cases are reported to the administration. This article seeks the awareness and risk factor regarding to the prevailing IV access failure using the PIVC. This manuscript reviewed the statistical data of PIVC dislodgement, significant of dislodgement, dislodgment cases among pediatric, medical staff factor related to PIVC dislodgement and alternative of securement device. This manuscript also discussed the needs of new securement device in order to reduce the percentage of PIVC dislodgement from occurs.
Objectives: There is little evidence in the medical literature about safety of PDA device closure and its effects on aortic root diameter in Marfan patients. We reported on nine Marfan patients whose ducts were occluded by coil or Amplatzer Duct Occluder.
Patients and interventions: Two patients had aneurismal type E ducts which were closed by a single coil, respectively. The others had conical ducts for which even Amplatzer occluder, stiff, or double coils were used.
Results: No untoward consequence was found during a median follow up period of 18.5 months (range 3 months to 6.33 years). Two patients had small residual shunts. The observed change in the mean ratio of aortic root diameter to its estimated value was statistically insignificant in seven patients who had complete data on their aortic root diameter before PDA closure and during the follow up.
Conclusions: We concluded that PDA device closure in Marfan patients is safe. Risk of residual shunt is higher even after closure of small ducts.
Background: Peripheral venous catheterisation is indispensable in modern practise of medicine. The indications of venous access should be weighed against the risk of complications, the commonest being thrombophlebitis. Thrombophlebitis causes patient discomfort and the need for new catheter insertion and risk of developing further widespread infections. Methodology: This observational study was conducted on adult patients admitted to the surgical and medical ward of a tertiary hospital in Negeri Sembilan Malaysia in 2011. Four researchers visited patients daily and examined for signs of thrombophlebitis; warmth, erythema, swelling, tenderness or a palpable venous cord. Risks factors that were studied in this research were patient/s age and gender, duration of catheterization, use of catheter for infusion, size of catheter, site of catheter insertion and types of infusate. Thrombophlebitis was graded using a scale adapted from Bhandari et al. (1979). Results: In total, 428 patients were recruited with an incidence rate of thrombophlebitis of 35.2%. Among those who developed thrombophlebitis, 65% had mild thrombophlebitis, 19% moderate and 8% severe thrombophlebitis. Results showed that female patients had a significant increased risk of developing thrombophlebitis. Also risk increased significantly with increased duration of catheterization and usage of the catheter for infusion. The age of a patient, types of infusate use, size of catheter and site of catheter insertion did not significantly influence the development of thrombophlebitis. Conclusion: The study showed that risk of developing thrombophlebitis is significantly increased among female patients, and also with increased duration of catheterization and use of the peripheral venous catheter for infusion. We recommended elective replacement of catheter every 72 hours and daily examination of catheters for signs of thrombophlebitis by a healthcare personnel.
Central vein stenosis is not uncommon in hemodialysis-dependent patients as a result of mechanical damage to the vessel walls from prior cannulation. It can cause ipsilateral upper limb swelling and pain, resulting in suboptimal hemodialysis. It is unfortunate for bilateral central vein stenosis to develop concomitantly, and rare in the setting of an in-situ pacemaker. This case illustrates the successful ligation of a nondependent left arteriovenous fistula and stenting of the right subclavian vein with functioning ipsilateral arteriovenous fistula, to overcome the problem of symptomatic bilateral upper limb swelling.

Massive pulmonary embolism (PE) is not an uncommon condition, and it usually carries a high risk of mortality. It is one of the fatal conditions that commonly affect young patients. A definitive treatment for patients with massive PE is still lacking, and surgical intervention carries a substantial mortality risk. Thus, percutaneous intervention (clot fragmentation and/or aspiration) remains an option in some patients, specifically in those with a risk of bleeding, contraindicating the use of thrombolysis. There have been no randomized trials to validate percutaneous intervention in massive PE. A sufficient level of evidence is still lacking, and its use depends upon the expert committee's opinion and study of previous case reports. We present a 23-year-old man with first onset massive PE secondary to protein C deficiency, who was treated successfully with the combination of systemic thrombolysis and percutaneous interventions.
Central venous catheter placement is indicated in patients requiring long-term therapy. With repeated venous catheterisations, conventional venous access sites can be exhausted. This case illustrates the expanding role of radiology in managing difficult venous access. We present a case of translumbar, transhepatic, and transcollateral placement of central catheter in a woman with a difficult venous access problem who required lifelong parenteral nutrition secondary to short bowel syndrome. This case highlights the technical aspects of interventional radiology in vascular access management.

We present two infants whose endovascular lines were accidentally cut or fractured, and had to be retrieved via transcatheter means in the cardiac catheterisation laboratory. The first case was a two-month-old infant with transposition of the great arteries, requiring an emergency balloon atrial septostomy. An indwelling vascular catheter that was placed in the right femoral vein was accidentally cut and had migrated into the inferior vena cava, before being retrieved. The second case was a one-week-old neonate who presented with pneumonia at birth, and had a long intravenous catheter placed in the left saphenous vein, which became fractured, and subsequently migrated into the heart. This case presented as a pulmonary embolus with haemodynamic instability, as the catheter had partially obstructed the right ventricular outflow tract. This was later retrieved via transcatheter means.
The authors describe a newly developed expandable cannula to enable a more efficient use of an endoscope in removing intraparenchymal spontaneous hypertensive intracerebral hematomas. The cannula is introduced like a conventional brain cannula, using neuronavigation techniques to reach the targeted hematoma accurately, and, once deployed, conventional microsurgical techniques are used under direct endoscopic visualization. This method was used in 6 patients, and, based on the results of intraoperative intracranial pressure monitoring and postoperative CT scanning, the authors were able to achieve good hematoma removal. They found that by using the expandable cannula, efficient endoscopic surgery in the brain parenchyma was possible.
In the current study, we report a new technique to place a tunnelled peripherally inserted central catheter
(PICC) at the upper arm of patient under real-time ultrasound-guided venipuncture using disposal equipment
provided within a standard PICC set. The tunnelling of the PICC required an extra time of 5 minutes but was
well tolerated by all patients involved in the study. The tunnelled PICC was applied on 50 patients and the
infection rate as well its catheter dwell time were compared to another 50 patients with conventional PICC.
The rate of patients who developed infection decreased from 34% for conventional PICC to 16% in tunnelled
PICC patients. The central line-associated blood stream infections rate was also decreased from 4.4 per 1000
catheter-days for conventional PICC to 1.3 per 1000 catheter-days for tunnelled PICC. The mean time to infection
development for tunnelled PICC (24 days) was longer than those observed with conventional PICC (19 days).
Tunnelled PICC has also increased the mean catheter dwell time from 27 days (for conventional PICC) to 47
days. Tunnelling a PICC has the potential to reduce the infection rate while increase the catheter dwell time.

Continuous spinal anaesthesia using the incremental technique was used in nineteen high risk patients with multiple medical problems, seventeen of whom were elderly, for lower limb orthopaedic and pelvic surgery. An intrathecal catheter (18G/28G) was inserted under local anaesthesia via the lumbar interspinous space. Spinal anaesthesia was induced with small incremental doses of 0.5% bupivacaine hydrochloride through the intrathecal catheter to achieve the level of analgesia required for surgery. The duration of surgery ranged from 45 to 300 minutes (mean + S.D 100 + 37 min). The initial volume of 0.5% bupivacaine required for surgery ranged from 0.8 ml-2.0 ml (1.2 + 0.7 ml) and the total volume ranged from 0.9 ml to 3.1 ml (mean + S.D 1.4 + 0.7 ml). Haemodynamic stability was well maintained perioperatively. Only two patients required 6 mg of ephedrine and 1 mg of aramine respectively for a greater than 25% reduction in systolic blood pressure with induction of spinal anaesthesia. Intrathecal morphine 0.1-0.3 mg was administered to 15 patients at the end of surgery for postoperative pain relief with good effect. One patient developed late respiratory depression from an inadvertent overdose of intrathecal morphine. No neurological sequelae were noted and no patient developed a postdural puncture headache. The use of the microcatheter was discontinued in the U.S.A and Australia following four case reports of cauda equina syndrome with this technique. Current opinion, however, is that the reported cauda equina syndrome was due to the neurotoxic effects of lignocaine 5% that was used and not due to the microcatheter per se. Continuous spinal anaesthesia is now used widely in Europe when cardiovascular stability is desired in poor risk patients undergoing lower limb and lower abdominal surgery.
PURPOSE: To determine if adequate anesthesia and akinesia could be obtained using an inferonasal quadrant sub-Tenons anaesthesia for cataract surgery.
METHODS: The sub-Tenons method of local anaesthesia was used in 50 patients undergoing extracapsular cataract extraction and lens implantation. The technique following was that described by JD Stevens in his study of 50 patients. Posterior sub-Tenons space was approached through a conjunctival incision in the inferonasal quadrant and the anaesthetic solution delivered by an irrigating cannula. The patients were assessed for residual ocular movements just before surgery. Effectiveness of anaesthesia was assessed during surgery using a verbal pain rating score. Scoring was based on the concept of a visual analogue pain score chart.
RESULTS: Total akinesia was obtained in 20% patients and total anaesthesia in 24% patients. The remainder of the patients had adequate akinesia and anaesthesia to proceed with and complete the surgery.
CONCLUSION: This method provides satisfactory anaesthesia for cataract surgery.
Repeatedly catheterising the internal jugular vein percutaneously through the same site, between the heads of the sternomastoid, resulted in soft tissue cleavage planes. The catheter entered the pleural cavity from the superior vena cava, a site remote from the percutaneous entry.
The internal jugular line can be misplaced in spite of respiratory fluctuation, free flow, and reflux with the container lowered below cardiac level. Radiological confirmation is mandatory.
