Comparison of Parker Flex-Tip Endotracheal Tube to Standard Endotracheal Tube

Patients presenting for elective surgery requiring tracheal intubation will be randomized to one of two different endotracheal tubes (ETT).


The post-operative complication of a sore throat after endotracheal intubation is unfortunately common, with estimates ranging from 15-50%. Most estimates are in the order of 35-45%.(McHardy 1999, Higgins 2002) There is evidence that many patients do not report sore throat and/or vocal changes unless directly asked because surgical pain is more prominent and many patients may be unaware that intubation completed as part of the general anesthetic. (Harding 1987)

The Parker FlexTip® endotracheal tube (ETT) is formulated with a softer plastic at the distal tip as well as a laterally curved profile to reduce trauma during ETT advancement. (Makino 2003) This ETT has been shown to be faster during fibreoptic intubation, but complication of sore throat was not examined. (Kristensen 2003)

Our previous study (Jones 2007) demonstrated that modification of anesthetic techniques could reduce the incidence of post-operative sore throat in patients undergoing naso-tracheal intubation. We will now study the Parker Flex-Tip ETT to see if its use can also reduce the incidence of sore throat in patients undergoing oro-tracheal intubation.

Medical and Biotech [MESH] Definitions

A type of oropharyngeal airway that provides an alternative to endotracheal intubation and standard mask anesthesia in certain patients. It is introduced into the hypopharynx to form a seal around the larynx thus permitting spontaneous or positive pressure ventilation without penetration of the larynx or esophagus. It is used in place of a facemask in routine anesthesia. The advantages over standard mask anesthesia are better airway control, minimal anesthetic gas leakage, a secure airway during patient transport to the recovery area, and minimal postoperative problems.

Determination, by measurement or comparison with a standard, of the correct value of each scale reading on a meter or other measuring instrument; or determination of the settings of a control device that correspond to particular values of voltage, current, frequency or other output.

Groups that serve as a standard for comparison in experimental studies. They are similar in relevant characteristics to the experimental group but do not receive the experimental intervention.

The use of biological mechanisms, usually involving living organisms such as bacteria, for the reduction or regulation of the population of noxious, destructive, or dangerous pests. Environmental concerns have focused attention on natural forms of disease control as potentially safe and effective alternatives to chemical pesticides. This has led to increased efforts to develop control strategies that rely on natural predators and parasites or that involve genetically engineered microbial pest control agents.
