Space Surgery may involve gravity problems

This is the space age, and going deep into space can trigger gravity problems. A successful space mission warrants healthy astronauts.
If scientists can explore the Universe, or travel in space or live in space, the scientists can enable astronauts to perform surgeries there, also. The robotic surgery is an established trend in modern surgery and can be performed remotely. However, performing surgery at zero degree gravity requires much more advanced technology.
Prof. Adam Dubrowski, a surgeon of Mount Sinai Hospital is a keen researcher in the area. He is busy in conducting extensive research and simulations to solve this challenge on long space missions.
At present, all astronauts going on board of a spaceship get basic medical training on the ground, and a medical doctor is always there on the board with them. Any medical emergency is treatable on the spaceship itself, and surgery will be done by a remote controlled robot .But such an arrangement is not adequate to deal with the situations which may arise on longer expeditions.
In the deep space with zero gravity the situation is entirely diverse and intricate . Even, the robotic surgery is not possible as the signals from earth will take much longer time to travel to the spaceship.
The researchers are not sure about what will happen to tools, sutures or procedures on zero gravity.
The researchers at Carnegie Mellon University and the University of Louisville are busy in creating tools to perform surgery at zero gravity.
According to Prof James Antaki, the surgical procedures at zero gravity will be difficult. In deep space, it will be difficult to control infection of body fluids and blood.
The scientists have developed a safe surgical procedure, wherein the bleeding will be controlled by creating a pressurized aqueous environment within the surgical field, and the wound will be treated as an isolated entity.
The surgery system of Prof Adam Dubrowski is a milestone in this direction.
Initially, the astronauts will be adapted to zero gravity by placing them upside down to feel weightless. Second, zero gravity will be simulated in a colossal swimming pond with the mock-up of the NASA space station , and adjusting the buoyancy of a person by suspending him/her in water. Lastly, the trainee astronauts will be taught basic skills of surgery in parabolic flights, where a plane ascends and descends about 40 times. This movement creates a transient zero-gravity environment on descents.
Prof. Dubrowski has developed a series of simple and involved simulations. He allows his students to make use of skin patches for stitching in surgeries at his Surgical Skills centre. He is making every effort to devise a procedure for successful surgery in space, before the next mission to the moon or Mars takes off.
Meanwhile, the Canadian Space Agency is creating a surgery training etiquette for astronauts and Dubrowski, Gray and Carnahan with the support of Wilson Centre and Surgical Skills Foundation.
Prof. Dubrowski is optimistic about the possibility of surgery in space for longer space missions. He is hopeful that better surgical skills shall be evolved before the manned lunar base on the moon takes off.
