| Abstract | The administration of local anesthetic before surgery to the great toe is often associated with significant difficulties, delaying surgery and increasing risk. Anxious patients can faint, refuse injection, or withdraw the foot while an anesthetic is being delivered. Such events led us to consider whether delivering a small amount of anesthetic throughout the injection site, before the main injection, may reduce pain intensity and duration. This study was designed to test this possibility. A randomized controlled, single-blinded, parallel-grouped clinical trial was carried out with a sample of 50 patients. All study participants received each injection method (1 or 2 stage) to either the medial or lateral side of the great toe. The primary end points were pain intensity, measured by scores on a visual analogue scale and duration, recorded by the patient with a stopwatch. The 2-stage method was associated with less intense pain (reduced from moderate to mild visual analogue scale level) of a shorter duration. The differences were highly statistically significant. In the 2-stage method, it is believed that they were due to the initial infiltration of a small quantity of the anesthetic solution throughout the injection site, with the remainder being administered, after a 2-minute interval, into tissue that was predominantly anesthetized. This differs from raising a traditional bleb where a small amount of anesthetic is infiltrated into superficial tissue. The 2-stage technique is therefore recommended as the method of choice for adults. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
