Abstract
Monopulmonary patients undergoing major abdominal surgery represent a high-risk population. While general anesthesia is typically the standard approach, mechanical ventilation can cause significant complications, particularly in patients with pre-existing lung conditions. Tailored anesthesia strategies are essential to mitigate these risks and preserve respiratory function. We present the case of a 71-year-old female with a history of prior right pneumonectomy for lung cancer. She was scheduled for combined left nephrectomy and left hemicolectomy laparotomic surgery because of extended colon cancer. The patient was prepared according to the local Enhanced Recovery After Surgery (ERAS) protocol and underwent thoracic neuraxial anesthesia with sedation maintaining spontaneous breathing, so avoiding general anesthesia and mechanical ventilation. Anesthesia in the surgical field was effective, and no respiratory problems occurred intraoperatively. The patient's rapid recovery and early discharge underscore the success of our "tailored anesthesia strategy." Our experience highlights the feasibility and benefits of tailored anesthesia in monopulmonary patients undergoing major abdominal surgery. By avoiding general anesthesia and mechanical ventilation, we mitigated risks and optimized patient outcomes, emphasizing the importance of individualized approaches in high-risk surgical populations.

Comparison of the effect of dexmedetomidine intrathecal injection and intravenous infusion on subarachnoid blockade during knee arthroscopy procedures: a randomized controlled trial. BMC Anesthesiol 2024; 24:16. [PMID: 38182994 PMCID: PMC10768377 DOI: 10.1186/s12871-023-02401-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2023] [Accepted: 12/30/2023] [Indexed: 01/07/2024] Open
Abstract
BACKGROUND Comparison of whether intrathecal dexmedetomidine prolongs spinal anesthesia-associated sensorimotor blockade more than intravenous infusion during knee arthroscopy procedures performed under subarachnoid blockade. METHODS Ninety patients aged 18-75 years, ASA class I-II, who underwent knee arthroscopy between October 2022 and April 2023 were randomized into intrathecal、intravenous and control groups.Subjects received three modes of administration: an intrathecal group (2 ml of 1% ropivacaine + 1 ml of 5 μg dexmedetomidine, along with intravenous saline infusion), an intravenous group (intrathecal 2 ml of 1% ropivacaine + 1 ml of 0.9% saline, with dexmedetomidine pumped intravenously at a dose of 0.5 μg/kg/h), and a control group (intrathecal 2 ml of 1% ropivacaine + 1 ml of 0.9% saline, along with intravenous saline infusion). Total analgesic duration, duration of sensory and motor blockade, Ramsay sedation score, Visual Analogue Score (VAS) at different postoperative time points, and occurrence of adverse effects were recorded. RESULTS The total analgesia duration was significantly longer in the intrathecal group than in the intravenous and control groups (352.13 ± 51.70 min VS 273.47 ± 62.57 min VS 241.41 ± 59.22 min, P < 0.001).The onset of sensory block was shorter in the intrathecal group than in the intravenous and control groups (4 [3-4]min VS 5 [4-5]min VS 5 [4-5]min; P < 0.001);the onset of motor block was shorter in the intrathecal group than in the intravenous group and the control group (5 [4-5]min VS 5 [5-6]min VS 6[5.5-7]min; P < 0.001).Sedation scores were higher in the intravenous group than in the intrathecal and control groups (P < 0.001). At 5 h postoperatively, the VAS score in the intrathecal group was lower than that in the intravenous and control groups (P < 0.001). At 24 h postoperatively, the VAS score in the intrathecal group was lower than that in the control group (P < 0.001). In addition, the incidence of bradycardia was significantly higher in the intravenous group than in the intrathecal and control groups (30%, 6.5%, and 3.4%, respectively; P = 0.018, P = 0.007). CONCLUSIONS Intrathecal administration of dexmedetomidine did prolong the total analgesia duration, as well as accelerate the onset of sensory-motor blockade compared with intravenous infusion, and did not result in any hemodynamic instability or other adverse events at the doses studied. TRIAL REGISTRATION This single-center, prospective, RCT has completed the registration of the Chinese Clinical Trial Center at 26/09/2023 with the registration number ChiCTR2300076170.

Abstract
Background Postoperative pain management is vital to improve patient care. Successful postoperative pain relief is currently achieved only through NSAIDs and narcotics. Objectives We compared dexmedetomidine and clonidine as additives to hyperbaric levobupivicaine 0.5% for the sub-arachnoid block (spinal anesthesia) concerning the onset time, duration of the block, hemodynamic changes, level of sedation intraoperatively and postoperatively and time taken for the first postoperative analgesic request and frequency. Methods This prospective, double-blind study enrolled 60 patients who underwent lower abdominal surgeries and were eligible for a sub-arachnoid block. They were allocated randomly to one of the two groups. Group D received intrathecal dexmedetomidine 5 µg and 0.5% hyperbaric levobupivicaine 15 mg. Group C received intrathecal clonidine 50 µg and 0.5% hyperbaric levobupivicaine 15 mg. Results Patients who received dexmedetomidine had a longer duration of the block (2-segment regression: 135 ± 15 min vs. 130 ± 20 min, S1 segment regression: 305 ± 50.4 min vs. 290 ± 47.2 min, Bromage 0: 285 ± 60 min vs. 280 ± 45 min), delayed first rescue analgesia request (700 ± 160 min vs. 506 ± 112 min), reduced frequency of rescue analgesics (1 vs. 2), and desired level of sedation (1.3 ± 0.46 vs. 0.4 ± 0.01) when compared to those receiving clonidine. There were insignificant differences between the groups in intraoperative hemodynamic parameters, such as minimal bradycardia and minimal hypotension. Though dexmedetomidine had an early onset, there was no statistically significant difference compared to clonidine. Conclusions Comparing dexmedetomidine and clonidine as additives in the sub-arachnoid block, the group who received dexmedetomidine had similar onset, prolonged duration of blockade, delayed first rescue analgesia demand, reduced frequency of analgesics, and desired sedation with similar minimal hemodynamic changes such as bradycardia and hypotension.

Abstract
Background and aim: There is an unmet need to prolong analgesia duration following regional anesthesia; dexmedetomidine as an adjuvant for the intrathecal block has gained popularity over the last few years. The present study compares the onset, duration of sensory and motor block, postoperative analgesia, hemodynamic changes, and adverse effect of dexmedetomidine or fentanyl as an adjuvant to hyperbaric bupivacaine administered intrathecally. Methods: With approvals, 60 American Society of Anesthesiologists (ASA) physical status I and II adult patients undergoing lower limb surgeries under subarachnoid block were randomized to receive either 5 µg dexmedetomidine (group BD, n=30) or 25 μg fentanyl (group BF, n=30) intrathecally along with 12.5 mg hyperbaric bupivacaine. The time to onset of sensory and motor blockade, time to peak block, intraoperative hemodynamic variations, duration of postoperative analgesia, and associated intraoperative and postoperative complications, if any, were recorded and compared statistically. SPSS v16 (IBM Corp., New York, United States) was used, and P<0.05 was considered significant. Results: The onset of sensory block in group BD was 1.54 ±0.38 minutes and 3.4 ± 0.40 minutes (P<0.001) in group BF. Time taken for the sensory level to reach T10 in group BD was 3.11± 0.43 minutes and 5.55 ± 0.60 minutes (P<0.001) in group BF. Time taken for two-segment regression in group BD was 160.06 ± 6.85 minutes and 110.4 ± 6.03 minutes (P<0.001) in group BF. The onset of motor block was 2.58 ± 0.437 minutes in group BD and 4.43 ± 0.43 minutes (P<0.001) in group BF. The total duration of analgesia in group BD was 365.8 ± 24.76 minutes and 213.33 ± 20.19 minutes (P<0.001) in group BF. Minimum intraoperative hemodynamic variations were found in group BD, and two groups had comparable side effects. Conclusion: Dexmedetomidine 5 μg added to intrathecal bupivacaine produced early-onset and prolonged block compared with fentanyl 25 μg. No significant attributable adverse effects were noted for both the drugs except the fall in blood pressure, which was gradual in dexmedetomidine but a steep fall in fentanyl.

Abstract
OBJECTIVE α2‑agonists and opioids have been used as intrathecal adjuvants to local anesthetics for several years, but the effect of intrathecal dexmedetomidine (Dex) or sufentanil combined with epidural ropivacaine in labor analgesia is not fully understood. METHODS A total of 108 parturient women receiving combined spinal-epidural labor analgesia were randomly divided into three groups. Group C received l mL saline (0.9%) intrathecally, Group D received 5 µg Dex intrathecally, and Group S received 5 µg sufentanil intrathecally. All parturient women then received 0.1% epidural ropivacaine and 0.2 µg/mL sufentanil for patient-controlled epidural analgesia with standard settings. The visual analog scale score, onset time, duration of intrathecal injection, local anesthetic requirements, and side effects were recorded. RESULTS The labor analgesia effects in Groups D and S were better than those in Group C. Groups D and S displayed significantly shorter onset times, longer durations of intrathecal injection, and reduced local anesthetic requirements compared with Group C. The incidence of shivering and pruritus in Group D was lower than that in Group S. CONCLUSION Intrathecal administration of 5 µg Dex could improve epidural labor analgesia effects.This randomized controlled clinical trial was registered with the Chinese Clinical Registry Center (ChiCTR-1800014943, http://www.chictr.org.cn/).

Anesth Essays Res 2020; 14:497-503. [PMID: 34092865 PMCID: PMC8159054 DOI: 10.4103/aer.aer_85_20] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2020] [Revised: 10/17/2020] [Accepted: 10/21/2020] [Indexed: 11/29/2022] Open
Abstract
Background: Dexmedetomidine is widely used as an adjunct to general as well as regional anesthesia. Aims: This study was conducted to compare and evaluate the synergistic effect of single intravenous (i.v.) bolus dose of dexmedetomidine with midazolam on spinal block duration, analgesia, and sedation in patients undergoing infra-umbilical surgeries. Settings and Design: Prospective, randomized, comparative, and double-blinded study. Materials and Methods: One hundred patients between 18 and 60 years of age of American Society of Anesthesiologists physical status I and II posted for elective infra-umbilical surgery under subarachnoid block were randomly divided into two groups (Group D and Group M). Patients of Group D received i.v. dexmedetomidine 0.5 μg.kg−1 and of Group M received i.v. midazolam 0.05 mg.kg−1 as premedication 5 min before spinal anesthesia over 10 min. Vital parameters, Ramsay sedation score, level of sensory and motor block, recovery time for sensory blockade, postoperative numerical rating scale, time of requirement of the first dose of postoperative rescue analgesic, and duration of analgesia were recorded and analyzed. Statistical Analysis: Chi-square test, t-test, and analysis of variance test were applied to analyze data using SPSS package for Windows. Results and Conclusion: Premedication with single i.v. dexmedetomidine prolonged the duration and increased the maximum upper level of only sensory component of spinal anesthesia (6.42 ± 3.21 vs. 4.8 ± 1.21 thoracic segments higher than with midazolam sedation). This property can be beneficial in preventing undesirable prolongation of motor block and facilitating early ambulation in shorter duration of infra-umbilical surgeries. In addition, dexmedetomidine slowed the regression of sensory block and increased the time of the first request of analgesic.

Abstract
Patients who have refractory cancer pain suffer both physically and psychologically. Cancer pain management has improved over the past few decades. However, the treatment of refractory cancer pain is still challenging all over the world. Intraspinal analgesia has become an effective strategy to treat refractory pain in patients with cancer. In this report, we present a patient receiving a large dose of intrathecal opioids for refractory cancer pain, and who is also afflicted with pain-induced depression. Dexmedetomidine (DEX) was used as part of a multimodal analgesic regimen that successfully alleviated both the patient's pain and depression. An intrathecal infusion of DEX may serve as an adjuvant drug in the treatment of cancer pain and pain-related depression.
