Randomized Controlled Trial Comparative Study
Comparison between preloading with 10 ml/kg and 20 ml/kg of Ringer's lactate in preventing hypotension during spinal anaesthesia for caesarean section.
This prospective, randomized, study was designed to compare the effect of two different preloading volumes of Ringer's lactate for prevention of maternal hypotension induced by spinal anaesthesia for Caesarean section. Eighty ASA I or II obstetric patients were randomized to two groups. Group 1 (n = 40) received 20 ml/kg of Ringer's lactate and Group 2 (n = 40) 10 ml/kg of Ringer's lactate over 20 minutes before spinal anaesthesia. ⋯ The difference in frequency of requirement for treatment of hypotension was not statistically significant. There were five patients in Group 1 and six patients in Group 2 who experienced nausea and vomiting, the frequency of occurrence did not show any statistically significant difference between the two groups. In conclusion, for prevention of hypotension during spinal anaesthesia for Caesarean section, infusing 20 ml/kg or 10 ml/kg of Ringer's Lactate gave similar results and we do not recommend the use of a larger volume of crystalloid for preloading before spinal anaesthesia.

Facial nerve palsy with a parotid mass is usually associated with malignant neoplasm of parotid gland. Its occurrence as a complication of parotid abscess is extremely rare. ⋯ We present a case of deep parotid abscess which is complicated by facial nerve dysfunction. Underlying neoplasia was excluded.
