Abstract Background We investigated the most effective suction pressure for preventing or promptly improving postoperative air leaks on digital drainage devices after lung resection. Methods We retrospectively analyzed the postoperative data of 242 patients who were monitored with a digital drainage system after pulmonary resection in our institution between December 2017 and June 2020. We divided the patients into three groups according to the suction pressure used: A (low-pressure suction group: − 5 cm H2O), B (intermediate-pressure group: − 10 cm H2O), and C (high-pressure suction group: − 20 cm H2O). We evaluated the duration of air leaks, timing of chest tube replacement, the amount of postoperative air leak, volume of fluid drained before chest tube removal, and the total number of air leaks during drainage. Results In total, 217 patients were included in this study. The duration of air leaks gradually decreased with significant difference between the groups, the highest decrease in A, the lowest decrease in C (P = 0.019). Timing of chest tube replacement, on the other hand, did not significantly differ between the three groups (P = 0.126). The number of postoperative air leaks just after surgery did not significantly differ between the three groups (P = 0.175), but the number of air leaks on postoperative day 1 were fewest in group A, then B, and greatest in group C (P = 0.033). The maximum amount of air leaks during drainage was lowest in A, then B, and highest in C (P = 0.036). Volume of fluid drained before chest tube removal did not significantly differ between the three groups (P = 0.986). Conclusion Low-pressure suction after pulmonary resection seems to avoid or promptly improve postoperative air leaks in digital drainage devices after lung resection. Trial registration This is a single-institution, retrospective analysis-based study of data from an electronic database. Study protocol was approved by the Akashi Medical Center Institutional Research Ethics Board (approval number: 2020–9).

Introduction: The number of chest trauma patients has rapidly increased in this 21st century of high speed travel, violence, natural and manmade disasters. Most of the patients present with haemothorax and/or haemopneumothorax. Drainage of haemothorax and/or haemopnumothorax by tube thoracostomy is the main stay of treatment. Even timely insertion of chest tube sometimes fails to drain haemothorax adequately and results in clotted haemothorax for which surgical management is needed. Application of continuous low pressure suction through chest tube hastens evacuation of blood and reduces incidence of clotted haemothorax and thoracotomy.Objective: The aim of this study is to find out the effectiveness of continuous low pressure suction in evacuation of blood and air from pleural cavity, in early re-expansion of lung and reduction of clotted haemothorax in comparison with simple chest tube drainage.Methods: This randomized controlled clinical trial was conducted at Combined Military Hospital (CMH) Dhaka and National Institute of Diseases of the Chest and Hospital (NIDCH), Mohakali, Dhaka from April 2012 to March 2013. A total of 60 patients with blunt and penetrating chest trauma fulfilling the selection criteria enrolled in this study. Patients were allocated into two groups. Patients who received continuous low pressure suction on their chest tubes were leveled as group-I and patients who received only chest tube drainage were leveled as group-II. Data were collected by interview, observation, clinical examination and investigation results. Data were processed and analyzed by using statistical test.Results: The mean chest tube duration was 7.13±2.1 days with a range from 5-16 days in group-I as compared to 11.83±5.26 days with a range from 6-28 days in group-II. The mean duration of hospital stay was 8.97±2.28 days with a range from 6-18 days in group-I as opposed to 13.47±5.53 days with a range from 8-32 days in group-II. In group-I 96.7% patients achieved full lung re-expansion while 3.3% patients had clotted haemothorax for which they underwent thoracotomy and evacuation of clot. In group-II who was on simple chest tube drainage, 76.7% patients achieved full lung re-expansion and 23.3% patient had clotted haemothorax and required thoracotomy.Conclusion: Continuous low pressure suction is a useful device in the management of traumatic haemothorax and/or haemopneumothorax. It reduces morbidity, hospital stay and cost of thoracic surgery.Journal of Armed Forces Medical College Bangladesh Vol.10(2) 2014

Modification Of The Surface

The attack, on the surface of a polymer, by the atomic, molecular and ionic species that are created in a low pressure electrical discharge in a gas is interesting because: 1) significant interior morphological features may be revealed, 2) dielectric breakdown of polymeric insulation on high voltage power distribution lines involves the attack on the polymer of such species created in a corona discharge, 3) adhesive bonds formed between polymer surfaces subjected to such SDecies are much stronger than bonds between untreated surfaces, 4) the chemical modification of the surface creates a reactive surface to which a thin layer of another polymer may be bonded by glow discharge polymerization.

Field Ion Microscope

The field ion microscope, devised by Erwin Muller in the 1950's, was the first instrument to depict the structure of surfaces in atomic detail. An FIM image of a (111) plane of tungsten (Fig.l) is typical of what can be done by this microscope: for this small plane, every atom, at a separation of 4.48Å from its neighbors in the plane, is revealed. The image of the plane is highly enlarged, as it is projected on a phosphor screen with a radius of curvature more than a million times that of the sample. Müller achieved the resolution necessary to reveal individual atoms by imaging with ions, accommodated to the object at a low temperature. The ions are created at the sample surface by ionization of an inert image gas (usually helium), present at a low pressure (< 1 mTorr). at fields on the order of 4V/Å.
