complex surgery on global stage


VISAKHAPATNAM: Accident victims with multiple injuries are often known to suffer serious complications due to intra-abdominal pressure, despite there being no injury to the abdomen and despite them being under the best medical care.


Doctors attribute this to a condition known as Abdominal Compartment Syndrome (ACS), which requires complex surgical management. ACS is a known cause of multiple-organ dysfunction in 20-30% of poly-trauma (multiple injuries) cases, where the patient may not have any injury on the abdomen but still succumbs because of pressure building up inside the abdomen that constricts blood flow to the heart. By the time the complex surgery is undertaken, the patient might suffer multiple organ failure and die.

A city-based doctor and an alumnus of Andhra Medical College and All India Institute of Medical Sciences, Delhi, who has done extensive research on this, will present a paper on ACS at an international surgical conference being held in Turkey by the European Society for Surgical Research between May 29 and June 1. Dr Subhash Chandra Dadhich has been successful in reducing mortality in poly-trauma cases by surgically reducing the pressure inside the abdomen and easing blood supply to vital organs at the appropriate time.

Dr Dadhich's research, published in the Indian Journal of Surgery, emphasized on the right timing of the surgery - the cutoff point is when the intra-abdominal pressure rises to 25 mm mercury (25 mm hg) and one needs to be prepared for surgical management when the pressure reaches 16 mm hg.

"This abdominal surgery, where the intestines are brought out of the abdomen to normalise pressure and blood flow, is done usually in trauma cases. But by the time the surgery is undertaken, it becomes too late and often the patient succumbs. The surgeon and his team should realise the correct time for the surgery," said Dr G Arjuna, a general and laparoscopic surgeon at King George Hospital.

"As intra-abdominal pressure rises in some poly-trauma cases, the blood vessels get compressed, reducing blood supply to vital organs and leading to kidney and liver failure. Therefore, when the pressure rises to 25 mm hg, the abdomen is opened up vertically from the xiphisternal joint (the meeting point of the chest and abdomen) to the pelvic bone," said Dr Dadhich.

"A catheter in the urinary bladder connected to the monitor is used to check the intra-abdominal pressure. The swelled up intestines pop out of the abdomen. The abdomen is kept open for a few days with special suction dressing applied to it while the patient is in the ICU," he said.

"After a few days, the patient is taken back to the operation theatre and an attempt is made to close the abdomen. If this is not possible because of swelling, a split skin graft is taken from the patient's thighs and the abdomen is closed. This results in a ventral or incisional hernia and the patient is sent home with all precaution," said the surgeon.

"After six months, when the patient's pressure normalises and the swelling subsides, the patient is readmitted, the skin covering removed, intestines put back and the abdomen closed normally," Dadhich explained.

Hong Kong's first electric coach, known as an e-coach, is unveiled by CLP Power Hong Kong Ltd as part of a green initiative to promote wider use of environmentally-friendly transport.

Let's take a look at its key features:



Hong Kong’s first electric coach



Produces zero emissions

9 May, 2013
Powered solely by electricity, the 49-seat vehicle has a wealth of environmentally-friendly and energy-saving features. It produces zero emissions at street level, significantly improving roadside air quality compared to traditional diesel coaches.

Having no diesel engine, it also generates less noise and heat, providing a smoother and greener travelling experience. It is also more economical, with energy costs only 27 per cent of those of a diesel coach, and more energy efficient, converting 80 per cent of input energy compared to only 20 per cent in a diesel coach.

3-hour fill-up can run from 250 km to 300 km

Maintenance costs are also lower as it has no gear box or engine. After a three-hour fill-up at a quick charging station, the e-coach can run from 250 to 300 kilometres with its air-conditioning on, equivalent to four round trips between Mong Kok and Tin Shui Wai.

The e-coach will not only serve as a shuttle bus for employees but will also be used in a trial programme allowing business customers to take a ride on Hong Kong's first e-coach and experience its environmental benefits first-hand.

Don this mask for superhuman powers


WASHINGTON: 'Iron Man' fans, rejoice! Researchers claim to have developed two 3D printed masks that can give wearer superhuman sight and hearing.


One of the masks covers the wearer's ears, mouth and nose and uses a directional microphone to give him the ability to hear an isolated sound in a noisy environment. With the mask, developed by a group of students at the Royal College of Art in London, the user could select a person in a crowd and hear his words without any surrounding noise, 'Mashable' website reported.

The other prototype is to be worn over one's eyes. A camera captures video and sends it to a computer, which can apply a set of effects to it in real-time and send it back to the user.

The wearer can use the mask to see movement patterns, similar to the effects of long-exposure photography. The research team behind project Eidos - Tim Bouckley, Millie Clive-Smith, Mi Eun Kim and Yuta Sugawara - believe the technology has many possible applications.

The wearer could use the visual mask it to analyze movement and technique in sports. And concert-goers could use the hearing mask to focus on a certain performer at a concert, the report said.

"We are used to controlling the world around us to find the settings that suit us best.

"But while technology advances to aid this, our physical bodies remain the same. "What if we had the same control over our senses? If we could adjust them in real time, what experiences would this make possible," researchers said.
