Physical or chemical restraint of snakes is frequently required in order to follow safe protocols for a [[Snake Physical Examination|physical examination]].  The best method for transport of non-venomous and non-aggressive species is simply a cotton bag into which snakes will often retreat voluntarily.  Prior to handling any snake, it is important to establish the species or else a dangerous snakes may be inadvertently handled without due care. Ideally snakes should be handled minimally. Hypothermia is not a method of restraint. The oculovasal reflex is not seen in snakes. When handling a snake for the first time, it is safest to grasp just behind a snake’s head before lifting the rest of the body.

====One-handed technique restraint====

Most pet snakes are accustomed to some handling so in many instances restraint can be minimal.  While the snake is allowed to grip a wrist and forearm, the hand restrains the snake's head at the base of the skull.  The other hand is then free.

====Two-handed technique restraint====
 
−
A snake needs to be supported at a minimum of two points on the body.  One person can hold the body and move with the snake as it moves.  A second person uses minimal pressure to control the head.

Aggressive snakes should be restrained before they are removed from their transportation bag.  This is achieved by holding the head behind the occiput using the thumb and middle finger, while the index finger is placed on top of the head.  The larger pythons and anacondas can exceed 6m in length and 150kg in weight and are powerful and potentially dangerous.  For these animals, a second or even third handler will be required to support the body during the examination.  It is usually safer and more convenient to sedate a large pugnacious snake than to struffle on and risk injury to the snake, client or staff.

For particularly aggressive or poisonous snakes, clear plastic tubes are very useful.  The snake is lifted from its container with a snake hook and placed on the floor.  Clear plastic tubing that is just wider than the head of the snake is held in tongs in front of the snake's head.  As the snake crawls into the tube, both the tube and the snake are grabbed quickly with the head and upper part of the body within the tube.  Openings can be cut into the tube to allow the clinician access to the snake's body for examination or collection of samples.  Tubing may not be appropriate for some limber elapids because of the potential for turning within the tubing.  Gloves and nooses are best not used because of the potential for unintentional injury.

Physical restraint

Handling

Nonvenemous snakes should be physically restrained by holding the head at the quadrate/mandible level and supporting the body of the snake. For every three to four feet of snake body, an extra handler should be positioned to support the spine. A snake should never be handled by being placed around the neck of a human. The behaviour of the animal should be observed from a distance prior to grasping.

Large constrictors should only be handled when there are two people present. They are extremely powerful and a single handler is in danger of injury, even death. There may also be legal considerations regarding the possession of dangerous animals so ascertain that these are fulfilled.

Venomous snakes

Venomous snakes should obviously only be handled by experienced personnel with appropriate equipment and preferably be treated by experienced veterinarians. Proper identification of any venomous snakes is of the utmost importance. In case of a human bite, it is necessary to have access to antivenin. A veterinarian working with venomous snakes needs to be aware of the laws regarding dangerous animals. Possession of venomous snakes is regulated so make certain that the owner has the appropriate licences. Also check with the appropriate authorities if you, the veterinarian, need to be specially licensed to treat or house venomous snakes.

  • At least two people should always be involved in handling a venomous snake
  • Large, obvious signs that read "VENOMOUS SNAKE" should be placed on the outside of the enclosure
  • An emergency telephone with essential contact numbers should be located nearby of venomous snake enclosures
  • An antivenin protocol should be developed with a local hospital
