Design of drain tube with movable shutter in household refrigerators

Abstract Background Pulmonary tractotomy effectively treats deep pulmonary penetrating injuries; however, it requires the accurate insertion of forceps or a stapler into the wound tract. This report describes a case of tractotomy using the Penrose drain guide for a deep lung injury caused by chest drainage. Case presentation A 75-year-old man suffered multiple rib fractures and hemothorax. After admission, chest tube drainage was performed because the patient’s respiratory condition deteriorated due to increased right pleural effusion. However, as the chest tube was stabbing into the right upper lobe, a pulmonary tractotomy was performed to treat the injury. Cutting the visceral pleura just over the tip of the chest tube caused the tube to completely penetrate the lung. A Penrose drain tube was fixed to the chest tube, which was then removed. The Penrose drain tube completely penetrated the lung and was coupled to the anvil side of the stapler to guide it smoothly into the wound tract. After stapling left the wound tract open, selective suture ligation of the damaged vessel and bronchioles was performed. Conclusions Although the indications for tractotomy using the Penrose drain guide are limited, we believe that this technique can be useful in patients with deep stabbing or penetrating lung injuries with rod- or tube-shaped foreign body remnants.

AbstractIntroduction:Cholangiocarcinoma (CCA) or klatskin’s tumour involves malignant tumours at the liver hilum’s biliary confluence. Incidence of CCA results in unresectable tumours that require appropriate therapy to improve quality of life. The liver is considered as the most frequent site of tumour recurrence. Promising results of long-term survival have been established with computed tomography-guided high-dose-rate brachytherapy.Materials and methods:Intraluminal brachytherapy (ILBT) is performed through the percutaneous transhapatic bile duct drain tube (PTBD). The passage of the brachytherapy guide tube through the bile duct is more complex compared with oesophageal/endobronchial application.Results/discussion:It results in a recoiled view of the tube in the abdominal region of the computed tomography (CT) scan. Owing to inherent artefacts induced by metal stents in CT scans, intersected view is possible between the ILBT guide tube and the intra-hepatic drain tube. It would mislead the planner to track wrong passage that could result in fatal error.Conclusion:In this case study, we contoured the ILBT guide tube by cross-verifying its position with a digitally reconstructed radiograph (DRR) before catheter tracking. Thus, it ensures precise simulation of source dwell positions, thereby avoiding high-dose delivery to nearby vital organs such as intestines, liver hilum and blood vessels.

Temperature Probe

We determined the feasibility, accuracy and optimal location of oesophageal core temperature measurements using the ProSeal laryngeal mask airway drain tube. Thirty normothermic anaesthetized ventilated adults (ASA 1 to 2, aged 18 to 80 years) were studied. Temperatures were recorded using a thermistor at six different locations (middle of drain tube and at 0 to 20 cm distal to the drain tube in 5 cm increments) and compared to nasopharyngeal (thermistor) and aural (infrared tympanic thermometer) reference core temperatures. The temperature probe was successfully inserted into the oesophagus in all patients at the first attempt. Oesophageal temperature increased with depth from 0 to 5 cm (35.2 v 35.9, P<0.0001) and 5 to 10 cm (35.9 v 36.3, P<0.01), but was unchanged from 10 to 15 cm (36.3 v 36.6) and 15 to 20 cm (36.6 v 36.7). Aural temperature was higher than nasopharyngeal temperature (36.8 v 36.0, P<0.0001). Aural temperature was 0.89 to 1.59°C higher than the oesophagus at 0 to 5 cm and 0.21 to 0.30°C higher than the oesophagus at 15 to 20 cm. Nasopharyngeal temperature was 0.06 to 0.76°C higher than the oesophagus at 0 to 5 cm and 0.62 to 0.84°C lower than the oesophagus at 15 to 20 cm. The lowest temperature was in the mid-point of the drain tube (34.7). We conclude that oesophageal core temperature measurement is feasible and accurate using the ProSeal laryngeal mask airway. The optimal location for the temperature probe is at 15 to 20 cm.

Early Closure

Postoperative surgical site infections (SSIs) are one of the most common complications. SSIs after laparotomy have a high incidence and are complicated and expensive to heal. The aim of this study was to evaluate the safety and efficacy of a novel therapy of early closure of open abdominal SSIs wound combining wound irrigation with negative pressure wound therapy (NPWT). Open abdominal SSIs wounds were closed with sutures in 42 consecutive patients. Topical NPWT was applied over a closed wound with a deep drain to allow dynamic drainage and wound irrigation. CT scan with contrast medium injected through the deep drain was performed in patients with suspicious tracts detected during debridement surgery three days after surgery to identify a potential fistula. Wound healing and safety of the therapy was evaluated during an average six months follow-up. Closed wounds healed successfully in all the patients without recurrence of wound infection. Fistulas were easily diagnosed in all four fistula patients by using CTscan with contrast medium injection through the wound. Fistula was confirmed in these four patients at re-exploration. All the drain tube wounds healed spontaneously after drain removal. No severe adverse event occurred during therapy in any patients. With the aid of topical NPWT and deep drainage and irrigation, early closure of open SSIs wound can be done safely. We were also able to diagnose gastrointestinal fistulas at an early stage with the use of CTscan imaging after contrast injection into the wound.
