“…[9][10][11] Being more hemodynamically stable with prolonged analgesia proven from various studies we thought of utilisation of the same to anaesthetise high risk geriatric patients who are at risk of these complications. Same was also supported by studies conducted by Kader AARA, et al and Srivastava N et al [12][13][14] in adult patients undergoing lower limb surgeries. To reduce the hemodynamic effects further we used preferential unilateral blockade technique to reduce the extend of sympathetic blockade.…”

Poor cardiopulmonary reserve, multiple comorbidities and polypharmacy in geriatric patients result in significant hemodynamic changes after the subarachnoid block (SAB) which are often unpredictable and requires administration of fluids, vasopressors, invasive monitoring and ICU admission leading to poor post operative outcome especially in patients belonging to American Society of Anaesthesiologists Physical Status (ASA PS) 3 & 4. Fractionated dose of hyperbaric bupivacaine for preferential unilateral lower limb blockade is found to have excellent hemodynamic stability and more duration of action making it a better alternative to the bolus dose in unilateral hip surgeries in high-risk geriatric patients. Here is a case series of 20 high risk geriatric patients who successfully underwent unilateral hip surgeries under fractionated dose of spinal anaesthesia with a stable perioperative hemodynamics.

Background and Aims: Spinal anaesthesia (SA) stands as a widely utilised anaesthetic approach for patients undergoing surgeries involving the lower limb, lower abdomen, pelvis and perineum. This study aims to evaluate the safety of fractionated dose versus bolus dose injection of hyperbaric bupivacaine (0.5%) with buprenorphine in SA for lower limb surgeries concerning haemodynamic stability, total analgesia duration and the quality of sensory and motor blocks. Materials and Methods: A randomised controlled trial was conducted from January 2023 to January 2024 after obtaining approval from the Institutional Ethics Committee, adhering to ethical standards throughout the research process. A sample size of 54 per group was determined accounting for potential dropouts, considering a dropout rate of 10%. The criteria for participant selection were carefully established. Inclusion criteria encompassed patients who had undergone lower limb surgeries and had American Society of Anesthesiologists (ASA) physical status 1 and 2, were aged between 18 and 60 years, had a body mass index (BMI) falling within the range of 18.5 to 24.9 kg/m 2 , and had a height ranging from 150 to 180 cm. Results: In our investigation, we observed that five minutes after administering SA, the sensory level was notably elevated in the fractionated group, with a majority of patients (62.9%) reaching a level of T10. Simultaneously, the corresponding motor block, assessed using the modified Bromage score, predominantly showed a score of 4 in the fractionated group, with 77.10% of patients exhibiting this level, compared to 62.90% in the bolus group. By the 20-minute mark post-SA, the majority of patients in the fractionated group had sensory levels at either T8 or T10, while in the bolus group, an equal number of patients (40%) had reached these levels, and around 5.7% even displayed a level at approximately T6. Conclusion: In conclusion, when comparing the patients in Group F [fractionated dose of bupivacaine and buprenorphine] to those in Group B [bolus dose of bupivacaine and buprenorphine], the patients in Group F exhibited a higher level of haemodynamic stability.
