Nitroglycerin versus milrinone for low central venous pressure in patients undergoing laparoscopic hepatectomy: a double-blinded randomized controlled trial. BMC Anesthesiol 2024; 24:244. [PMID: 39026144 PMCID: PMC11256614 DOI: 10.1186/s12871-024-02631-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2024] [Accepted: 07/10/2024] [Indexed: 07/20/2024] Open
Abstract
BACKGROUND Conventional anesthesia used to reduce central venous pressure (CVP) during hepatectomy includes fluid restriction and vasodilator drugs, which can lead to a reduction in blood perfusion in vital organs and may counteract the benefits of low blood loss. In this study, we hypothesized that milrinone is feasible and effective in controlling low CVP (LCVP) during laparoscopic hepatectomy (LH). Compared with conventional anesthesia such as nitroglycerin, milrinone is beneficial in terms of intraoperative blood loss, surgical environment, hemodynamic stability, and patients' recovery. METHODS In total, 68 patients undergoing LH under LCVP were randomly divided into the milrinone group (n = 34) and the nitroglycerin group (n = 34). Milrinone was infused with a loading dose of 10 µg/kg followed by a maintenance dose of 0.2-0.5 µg/kg/min and nitroglycerin was administered at a rate of 0.2-0.5 µg/kg/min until the liver lesions were removed. The characteristics of patients, surgery, intraoperative vital signs, blood loss, the condition of the surgical field, the dosage of norepinephrine, perioperative laboratory data, and postoperative complications were compared between groups. Blood loss during LH was considered the primary outcome. RESULTS Blood loss during hepatectomy and total blood loss were significantly lower in the milrinone group compared with those in the nitroglycerin group (P < 0.05). Both the nitroglycerin group and milrinone group exerted similar CVP (P > 0.05). Nevertheless, the milrinone group had better surgical field grading during liver resection (P < 0.05) and also exhibited higher cardiac index and cardiac output during the surgery (P < 0.05). Significant differences were also found in terms of fluids administered during hepatectomy, urine volume during hepatectomy, total urine volume, and norepinephrine dosage used in the surgery between the two groups. The two groups showed a similar incidence of postoperative complications (P > 0.05). CONCLUSION Our findings indicate that the intraoperative infusion of milrinone can help in maintaining an LCVP and hemodynamic stability during LH while reducing intraoperative blood loss and providing a better surgical field compared with nitroglycerin.

Abstract
Objective To determine the intravenous (i.v.) dose of esmolol needed to attenuate blood loss in patients undergoing posterior lumbar internal fixation (PLIF) surgery. Methods This study randomized patients to either the E5 or E10 group. Patients in the E5 group received a 0.25 mg/kg i.v. loading dose of esmolol before anaesthesia, followed by an infusion of 5 µg/kg/min throughout the operation. Patients in the E10 group received a 0.5 mg/kg i.v. loading dose of esmolol before anaesthesia, followed by an infusion of 10 µg/kg/min throughout the operation. Results The study analysed 33 patients: 16 in the E5 group and 17 in the E10 group. The mean ± SD blood loss at the end of surgery was significantly greater in the E5 than E10 group (586.3 ± 160.1 versus 347.7 ± 138.0 ml, respectively). The total amount of patient-controlled analgesia (PCA) used was significantly higher in the E5 than E10 group at 8 (26.1 ± 12.0 versus 17.5 ± 8.3 ml, respectively), 24 (58.4 ± 21.3 versus 44.1 ± 16.2 ml, respectively) and 48 h after surgery (90.0 ± 22.5 versus 69.3 ± 22.1 ml, respectively). Conclusion A continuous infusion of 10 µg/kg/min of esmolol can safely reduce blood loss during PLIF surgery. It was also shown to reduce postoperative PCA consumption.

Abstract
With advances in tumor treatment, metastasis to bone is increasing, and surgery has become the only choice for most terminal patients. However, spinal surgery has a high risk and is prone to heavy bleeding. Controlled hypotension during surgery has outstanding advantages in reducing intraoperative bleeding and ensuring a clear field of vision, thus avoiding damage to important nerves and vessels. Antihypertensive drugs should be carefully selected after considering the patient's age, different diseases, etc, and a single or combined regimen can be used. Hypotension also inevitably leads to a decrease in perfusion of important organs, so the threshold of hypotension and the maintenance time of hypotension should be strictly limited, and the monitoring of important organs during the operation is particularly important. Information such as blood perfusion, blood oxygen saturation, cardiac output, and neurophysiological conduction potential changes should be obtained in a timely fashion, which will help to reduce the risk of hypotension. In short, when applying controlled hypotension, it is necessary to choose an appropriate threshold and duration, and appropriate monitoring should be conducted during the operation to ensure the safety of the patient.

Abstract
BACKGROUND The effects of restrictive fluid therapy combined with controlled hypotension in the elderly on systemic oxygen metabolism and renal function are clinical concerns. The aim of this study was to evaluate blood loss, oxygen metabolism, and renal function in different levels of controlled hypotension induced by intravenous nitroglycerin, in combination with limited infusion, in elderly patients undergoing posterior lumbar fusion. METHODS A total of 40 patients, aged 60-75 with ASA grade II or III, who were planned for posterior lumbar fusion were randomly allocated into two groups: experimental group [target mean arterial pressure 65 mmHg (MAP 65) or control group (MAP 75)]. Indicators for blood loss, hemodynamic, systemic oxygen metabolism, and renal function evaluation index were recorded before operation (T0), 1 h after induced hypotension (T1), 2 h after hypotension (T2), and in recovery (T3). We compared changes in these parameters between groups to evaluate the combined effects of controlled hypotension with restrictive infusion. RESULTS CI, DO2I, and VO2I were lower in both groups at T1-T3 compared with T0 (p < 0.05). DO2I and VO2I in the MAP 65 group were lower than the MAP 75 group after operation. In both groups, SCysC increased at T1, T2, and T3 (p < 0.05) compared with T0. CONCLUSIONS Restrictive transfusion and control MAP at 65 mmHg can slightly change in renal function and reduce the risk of insufficient oxygen supply and importantly have no significant effect on blood loss and postoperative complications.

Abstract
Pott's disease is the most common granulomatous spine infection caused by tubercle bacilli and is a common site of osseous tuberculosis, accounting for 50–60% of cases. The delay in establishing diagnosis and management results in complications such as spinal cord compression and spinal deformity. The aim of this narrative review is to discuss the perioperative concerns in patients for spine surgery. The literature source for this review was obtained via PubMed, Medline, Google Scholar, Cochrane database of systematic reviews, and textbooks until December 2019. On the literature search, we could not retrieve any review article specifically discussing the perioperative concerns of spinal tuberculosis. Therefore, the aim of the present narrative review is to discuss the perioperative concerns of patients for spine surgery along with the specific concerns related to spinal tuberculosis.

Abstract
OBJECTIVE To compare the effects of milrinone, sodium nitroprusside (SNP), and nitroglycerin (NTG) on induced hypotension, cerebral perfusion, and postoperative cognitive function in elderly patients undergoing spine surgery. METHODS Sixty patients >60 years scheduled for lumbar fusion surgery were assigned to receive milrinone (group M), SNP (group S), or NTG (group N). The administration of the study drug was initiated immediately after perivertebral muscle retraction and was stopped after completion of interbody fusion. Target blood pressure was a decrease of 30% in systolic blood pressure from baseline or mean blood pressure of 60 to 65 mm Hg. The regional cerebral venous oxygen saturation (rSVO2), as a measure of cerebral perfusion, and the change in perioperative Mini-Mental State Examination (MMSE) score, as a measure of postoperative cognitive function, were assessed. RESULTS During the administration of the study drug, the overall and lowest intraoperative rSVO2 values were significantly higher (P = .01 and P = .01, respectively), and the duration of rSVO2 <60% was shorter in group M than in the other groups (P = .03). In group M, intraoperative rSVO2 was not different from the basal value, whereas in groups S and N, rSVO2 was significantly lower than the basal value during the administration of the study drug, but then returned to the basal value after terminating the study drug. Basal MMSE scores were comparable among the 3 groups. The MMSE score on postoperative day 5 was higher in group M than the other groups. CONCLUSIONS Milrinone used to induce hypotension resulted in better intraoperative cerebral perfusion and postoperative cognitive function compared to SNP and nitroglycerin.

Abstract
BACKGROUND Deliberate hypotension has been shown to reduce the intraoperative bleeding and the need for allogeneic blood transfusion, and improve the surgical field, but there is still controversy on its clinical safety. This systematic review was designed to assess the safety and benefits of deliberate hypotension for orthopedic surgery. METHODS The review met the requirements of the PRISMA guidelines. The Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, CINAHL, ISI Web of Science, ScienceDirect, and four Chinese databases (China National Knowledge Infrastructure, Wanfang, vip citation database, and updated version of China Biology Medicine disc from January 1, 2000 to January 1, 2019) were searched. All parallel randomized controlled trials comparing the effects of using deliberate hypotension with not using deliberate hypotension on clinical outcomes of patients undergoing orthopedic surgery were selected. The primary outcome was overall mortality. The secondary outcomes were the intraoperative blood loss, blood transfusion volume, and serious adverse postoperative events. RESULTS A total of 30 studies with 36 comparisons (1454 participants) were included in meta-analysis. Two studies with 120 participants reported overall mortality and the result was zero (low-quality evidence). The use of deliberate hypotension reduced the intraoperative blood loss (mean difference, - 376.7; 95% CI - 428.1 to - 325.3; I2 = 94%; 29 studies, 36 comparisons, and 1398 participants; low-quality evidence) and blood transfusion volume (mean difference, - 242.5; 95% CI - 302.5 to - 182.6; I2 = 95%; 13 studies, 14 comparisons, and 544 participants; low-quality evidence). Six studies with 286 participants reported the occurrence of serious adverse postoperative events and the result was zero (low-quality evidence). Subgroup analyses according to age groups, controlled mean artery pressure levels, types of orthopedic surgeries, different combinations of other blood conservative method, and hypotensive methods mostly did not explain heterogeneity; significant differences were identified in almost all subgroups. CONCLUSIONS Based on the available evidence, it is still unclear whether or not deliberate hypotension is a safe technique for orthopedic surgery due to limited studies with very small sample size, though it may decrease the intraoperative blood loss and blood transfusion volume irrespective of age groups, controlled mean artery pressure levels, types of surgeries, hypotensive methods, or different combinations of other blood conservation strategies.

Abstract
BACKGROUND The use of induced hypotension is limited because of concerns about hypoperfusion to major organs in elderly patients. The aim of this study was to compare the effects of milrinone with those of other vasodilating hypotensive agents on induced hypotension in elderly patients undergoing spine surgery. METHODS In total, 60 patients older than 60 years who underwent lumbar fusion surgeries were randomized to groups M (milrinone), S (sodium nitroprusside), and N (nitroglycerine). The study drug was infused after perivertebral muscle retraction until complete interbody fusion occurred. The infusion dose was adjusted to achieve a fall of 30% in systolic blood pressure or mean blood pressure to 60 to 65 mm Hg. Intraoperative blood loss, grade of the surgical field, and urine output were recorded. RESULTS Intraoperative blood loss per fused spine level was 288.5±94.4 mL in group M, 399.8±60.3 mL in group S, and 367.0±122.5 mL in group N (P=0.002). The grade of the surgical field was similar among the 3 groups (P=0.439). Hourly urine output was 1.4±0.5 mL in group M, 0.7±0.3 mL in group S, and 0.9±0.4 mL in group N (P<0.001). CONCLUSIONS The use of milrinone for induced hypotension led to less intraoperative blood loss and higher urine output than the use of sodium nitroprusside or nitroglycerine in elderly patients undergoing spine surgery.

Abstract
PURPOSE To estimate the incidence of instrumental spinal surgeries (ISS) and consecutive reoperations and to calculate the related resource utilization and costs. METHODS ISS and subsequent reoperations were identified retrospectively using surgery codes in claims data. The study period included January 01, 2009 to December 31, 2011. The reoperation rate was calculated for 1 year after the primary ISS. Resource utilization and costs were analyzed by group comparison. RESULTS A total of 3316 incident ISS patients were identified in 2010 with an annual reoperation rate of 9.98% (95% CI 8.98-11.02%). Mean costs per patient were €11,331 per ISS and €11,370 per reoperation, with €8432 directly attributed to the reoperation and €2938 to additional resources. CONCLUSIONS Costs of ISS and subsequent reoperations have a significant impact on health insurances budgets. The annual cost of reoperations exceeds the direct cost of the primary surgery driven by the need for further inpatient and outpatient care.

Abstract
Three column osteotomies (3CO) of the lumbar spine are powerful corrective procedures used in the treatment of kyphoscoliosis. Their efficacy comes at the cost of high reported complication rates, notably significant estimated blood loss (EBL). Previously reported techniques to reduce EBL have had modest efficacy. Here we describe a potential technique to decrease EBL during pedicle subtraction osteotomy (PSO) of the lumbar spine by means of pre-operative vertebral body embolization - a technique traditionally used to reduce blood loss prior to spinal column tumor resection. We present a 62-year-old man with iatrogenic kyphoscoliosis who underwent staged deformity correction. Stage 1 involved thoracolumbar instrumentation followed by transarterial embolization of the L4 vertebral body through bilateral segmental arteries. A combination of polyvinyl alcohol particles and Gelfoam (Pfizer, New York, NY, USA) were used. Following embolization there was decreased angiographic blood flow to the small vessels of the L4 vertebral body, while the segmental arteries remained patent. Stage 2 consisted of an L4 PSO and fusion. The EBL during the PSO procedure was 1L, which compared favorably to that during previous PSO at this institution as well as to quantities reported in previous literature. There have been no short term (5 month follow-up) complications attributable to the vertebral body embolization or surgical procedure. Although further investigation into this technique is required to better characterize its safety and efficacy in reducing EBL during 3CO, we believe this patient illustrates the potential utility of pre-operative vertebral embolization in the setting of non-oncologic deformity correction surgery.
