Recurrent ventricular arrhythmia can be fatal and cause serious complications, particularly when it is caused immediately after an operation. Incorrect placement of a Swan-Ganz catheter can trigger life-threatening ventricular arrhythmia, but even intensive care specialists tend to miss this fact. Here, we report a case of recurrent ventricular arrhythmia causing a severe hemodynamic compromise; the arrhythmia was induced by a severely angulated Swan-Ganz catheter. The recurrent ventricular arrhythmia was not controlled by any measures including repositioning of the catheter, until the complete removal of the Swan-Ganz catheter. It is necessary to keep in mind that the position of the pulmonary artery catheter should be promptly checked if there is intractable recurrent ventricular arrhythmia.

Purpose: The operative treatment for blow-out fracture involves restoration of intra-orbital soft tissue and bony structural integrity. There are several methods for reconstruction of inferior blow out fracture. We report reduction of inferior blow-out fracture with urinary balloon catheter in comparison with $Medpor^{(R)}$ using group to complication rate. Methods: A retrospective study was performed on 67 patients who underwent inferior orbital blow-out fracture reconstruction with $Medpor^{(R)}$ implant or urinary balloon catheter following between 2003 and 2006. Hospital records were reviewed especially for preoperative and postoperative enophthalmos, diplopia, extraocular muscle movement limitations, and hypoesthesia between $Medpor^{(R)}$ implant group and balloon catheter using group. Results: There was no significant statistical difference between both groups on incidence of postoperative complications of enophthalmos, diplopia, extraocular muscle movement limitations, and hypoesthesia. Postoperative infection, ectropion were absent in both groups.Conclusion: The use of urinary balloon catheter is simple, fast and inexpensive. Urinary balloon catheter is an alternative and reliable use for reduction of inferior orbital blow-out fracture.

Background: Continuous epidural block is widely used for surgical operation and postoperative pain management. The potential infection due to the epidural catheter is a definite harzard of continous epidural block. We investigated the effectiveness of bacterial filter in prevention of infection due to the epidural catheter. Methods: Patients scheduled for transabdominal hysterectomy were assigned to two groups by simple randomization (50 patients per group). All catheters were placed in the 2nd and 3rd lumbar epidural space, using careful sterile technique. Group 1 received injections by the epidural catheter with a bacterial filter and group 2 received injections by the epidural catheter without a bacterial filter. The infection rate in the tips of epidural catheter left for 3 days were compared between the two groups. Results: There was no significant difference in the infection rate between two groups. Conclusions: A bacterial filter of the epidural catheter for surgical anesthesia and postoperative analgesia dose not prevent all kinds of infection in continuous epidural block.

Percutaneous infraclavicular subclavian catheterization has been widely used for a total parenteral nutrition, hemodynamic monitoring and for venous access in difficult clinical situations. Many authors have claimed the infraclavicular cannulation of the subclavian vein in the tiniest infants can be performed with safety and ease, but there are always possibility of serious complications in this method. We present our experiences of peripheral venous cutdown with Broviac catheter. Author routinely introduced Broviac catheter into central vein via peripheral venous cutdown. There was no life threatening complications and no catheter related death. The complication rate was very low. The catheter related sepsis was documented in only two patient(4.7%). The average catheter longivity was 19.59 days. In view of the safety and low rate of complication, we think that peripheral venous cutdown with Broviac catheter should be the method of choice when central venous access is necessary in infants. The infraclavicular subclavian catheterization should be reserved in infants with few accessible peripheral vein.

The purpose of this study was to identify the proper changing time of tracheal suction catheter by examining the microorganisms inside after used The samples were the adult and the elderly patients who were in the intensive cane unit of one university hospital in Korea from the early December, 2002 to the end of May 2003. Since the patients needed tracheal suction, sterile catheter including other equipments were used whenever tracheal suction provided, to the experimental group. The sterile catheter with others was provided when the catheter repeatedly used for four hours, to the comparative group. Research was permitted by the head of hospital administration, hospital nursing department; microbiology and intensive care unit. The main results of the study are as follows. 1) The demographic characteristics between the two groups present statistically no difference. 2) Every the experimental group showed various kinds of microorganisms, the numbers of the kinds and carries of the microorganisms were less than those of the comparative group. 3) The mean numbers of the microorganisms between the two groups were significantly different, p < 0.05. This study results strongly emphasize the needs of using sterile catheter whenever a nurse suctions to keep patient's airway open.

Purpose: Surgery on digit requires a clear, bloodless field and it can be achieved by using a tourniquet. Several type of tourniquet have been used including Penrose drains and sterile glove with hemostat. We present a simple digital tourniquet using nelaton catheter, which is easily available, inexpensive, easy-to-apply, and effective for digital surgery. Methods: We made a small incision on the opposite side of an opening at the tip of nelaton catheter. Then the other tip of nelaton catheter is passed through the incision to form a ring. Nelaton catheter is placed aournd the base of the injured finger, making a tight circle to desired pressure. Results: A simple tourniquet using nelaton catheter effectively achieves a bloodless field and allows fine control of the pressure for digital surgery. Conclusion: We present a sismple digital tourniquet using nelaton catheter, which is easily available, inexpensive, tunable, and available for more than one finger.

Continuous epidural blockade is a widely accepted, useful technique for providing anesthesia and analgesia. But there have been several anecdotal reports of complications such as: abnormal position, knotting, shearing of the catheter, etc. We experienced a case of shearing of the end of an epidural catheter which was difficult to remove from epidural space of a 39-year-old patient. Ultrasonogram proved to be very effective to confirm the presence and position of the retained catheter. We surgically removed the retained catheter as it could potentially lead to infection of the epidural space. We advocate the ultrasonogram as an effective procedure to confirm and locate retained epidural catheter.

Intrathecal drug administration system (ITDAS) can reduce the side effects while increasing the effectiveness of opioids compared to systemic opioid administration. Therefore, the use of ITDAS has increased in the management of cancer pain and chronic intractable pain. Catheter obstruction is a serious complication of ITDAS. Here, we present a case of catheter obstruction by a mass formed at the side hole and in the lumen. A 37-year-old man suffering from failed back surgery syndrome received an ITDAS implantation, and the ITDAS was refilled with morphine every 3 months. When the patient visited the hospital 18 months after ITDAS implantation for a refill, the amount of delivered morphine sulfate was much less than expected. Movement of the pump rotor was examined with fluoroscopy; however, it was normal. CSF aspiration through the catheter access port was impossible. When the intrathecal catheter was removed, we observed that the side hole and lumen of the catheter was plugged.

Intravenous catheterization is a common procedure in human and veterinary medicine. Occasionally, a catheter might break within the blood vessel, and the fragment may cause embolization, infections, or other severe complications, and therefore must be removed promptly. For a successful and low-risk removal, the fragment should be localized accurately; however, ultrasound may be challenging to perform on small dogs due to inadequate probes. We report the case of a 2-year-old, 2.6 kg, intact female toy poodle that presented to the veterinary medical center owing to a recent onion intake; the owner requested to induce emesis. A 24 gauge peripheral intravenous catheter was inserted into the cephalic vein prior to the emetic injection. When the clinician removed the catheter, a device breakage was observed. A tourniquet was applied immediately proximal to the elbow. Ultrasonography was performed with a high-frequency small-footprint linear array transducer, also called a hockey-stick probe, to localize the fragment. An additional ultrasound was performed before surgery to confirm the location of the catheter piece, which migrated 5 cm proximally. Afterward, a surgical intervention allowed us to retrieve the fragment. This report highlights the effectiveness of a hockey-stick probe to determine the location of a catheter fragment in small breed dogs.
