Successful Spinal Block in Obstetric Patient with Past History of Scorpion Sting and Failed Spinal Anesthesia

Association between local anesthestic resistance and scorpion sting have been reported in literatures. Scorpion venom is known to affect the sodium channels in the nerve fibres and local anesthetics also acts on the same. But we report a case of successful spinal block in 23 years old second gravida posted for elective caesarean section with past history of failed spinal block and multiple scorpion sting 7 years and 2 years back. Last exposure was 4 months before previous caesarean section, thus failed spinal block may be due to recent exposure. Our conclusion is that, there is a direct relationship between duration of exposure to scorpion venom and susceptibility to local anesthetics.

The anthropometric measurements of tibia.

Anthropometry provides scientific method and technique for taking various measurements in different geographic regions and races. The Tibia itself is a complex anatomic unit so anthropometric study was devised on the same. In the present study 60 (26 right and 34 left) intact adult tibia were obtained from the bone bank of Anatomy Department of MGIMS, Sevagram. For this purpose a digital vernier caliper, osteometric board and measuring tape were used. The study was aimed at determining measurements for obtaining Cross-Section Index in middle, Cnemicus Index and Length-Thickness Index for both right and left Tibia. The details of data obtained with relevant review of literature will be discussed. The mean of Cross Sectional index for Right tibias was 102.90± 22.78. Similarly mean of Cross Sectional index for left tibias was 124.31± 25.06. The mean of Cnemicus Index for Right tibias was 66.17 ± 10.68 and for left side these values came out to be 67.31 ± 7.35. These are not statistically significant. The mean of Length-Thickness Index were 24.21 ± 0.96 and 24.43 ± 1.78 for right and left Tibias respectively.

A review of the chronology of epiphyseal union in the bones at knee and ankle joint.

Determination of the age of an individual from the appearance and the fusion of the ossification centres is a well accepted fact in the field of medical and legal professions. The process of formation of bones is called as “ossification”. Ossification of bone is a diagnostic tool for estimation of age until the process is complete for the particular bone. The long bones of lower limb play a vital role in assessment of age both in living and dry remains. Many scientists have tried to conclude there observations on bones of lower limb owing to differences in regional and environmental factors. Countable differences are noticed in the appearance and fusion activities of ossification centers depending on race geographic distribution and sex. Following is a review of works carried out so far in different regions of country as well as throughout the world.
