Background:The elderly represent a unique challenge for the effects of regional anesthesia, and very few cases of block onset delay have been described. Their delayed response is attributed to a number of factors that include: Physiologic deterioration, musculoskeletal contractures, degenerative joint disease, autonomic regulatory dysfunction, cognitive dysfunction, altered pharmacokinetics, and pharmacodynamics of local anesthetics and adjuvants.
Case Description:In this report we present the rare case of 45-min delay between the administration and onset of action of a subarachnoid blockade in a 103-year-old female, who was scheduled for left hip pinning, for repair of a femoral neck fracture. Patient received an injection of hyperbaric bupivacaine, 1.5 ml of 0.75% (11.25 mg), with 15 mcg of fentanyl into the subarachnoidal space and underwent the surgical procedure without complications.
Conclusions:Delayed responses to subarachnoid anesthesia can be expected in extremely elderly patients. Anesthetic procedures should be monitored and managed on a case-by-case basis.

In the United States, it has been estimated that the elderly population at 65 years and older will account for approximately 20% of total population by 2030, due to increased life expectancy and an aging baby boomer segment (Center for Disease Control and Prevention (CDC)). Life expectancy is longer as a result of improvements in the healthcare system, and we need to face the higher prevalence of chronic illnesses and disabilities along with increasing health care expenditures. Better understanding and management of physiologic and pathologic variations in geriatric populations are essential to fine-tune medical care, prevent complications and reduce morbidity and mortality.[
Neuraxial blockade consists of subarachnoidal and epidural injections. In subarachnoid anesthesia, medications are injected into the intrathecal space, in which lower doses of medications are required together for clinical efficiancy with decreased toxicity from each individual drug.[
Elderly surgical patients present specific challenges to anesthesiologists during and after surgery where they may suffer serious morbidity compared with their younger counterparts undergoing the same types of surgeries. Altered anatomical, physiological, and pharmacological aspects with increasing age complicate anesthetic procedures, whereas the optimal anesthetic methods have not been described.[
Limited literature is available on the effects of subarachnoid or general anesthesia in patients over 90 years of age. In this manuscript, we highlight the rare occurrence and presentation of a significantly delayed anesthetic onset in a 103-year-old woman with a hip fracture and with multiple co-morbid conditions.
A 103-year-old (body mass index [BMI]=27.2) African-American female from an assisted living home presented for left hip pinning of a femoral neck fracture following a fall from a wheelchair. Preoperative evaluation revealed an elderly women moaning in distress from severe excruciating left hip pain. After she was diagnosed with a left femoral neck fracture, she was scheduled for a hip pinning procedure under subarachnoid anesthesia. Past medical history was significant for hypertension, congestive heart failure, atrial fibrillation, osteoporosis, renal insufficiency, right lower extremity lymphedema with cellulitis, and peripheral vascular disease. She had a history of right tibial fracture and was taking furosemide, morphine, and enoxaparin. She had no history of known allergy.
Preoperative laboratory reports were significant for blood urea nitrogen (BUN) 35, creatinine (Cr) 1.75, hemoglobin (Hgb) 9.4, platelets 113, and international normalized ratio (INR) 1.1. Preoperative vital signs were blood pressure (BP) 120/70, heart rate (HR) 87. Blood gas analysis revealed a pH 7.39, CO240, PO285. In the operating room (OR) at 16:45, the patient was placed into the right lateral decubitus position. Approximately 500 ml of normal saline solution was given as preload prior to the spinal blockade. At 17:00 nasal cannula O2was administrerd, while maintaining good spontaneous ventilation and with 2 mg of midazolam injected intravenously. Following local skin infiltration, a 25G 5-inch Pencan brand spinal needle was used to access the subarachnoid space, with free flow of clear cerebrospinal fluid (CSF). Multiple attempts by an experienced, pain fellowship trained anesthesiologist were necessary to obtain CSF due to severe scoliosis and multiple bony osteophytes. Hyperbaric bupivacaine, 1.5 ml of 0.75% (11.25 mg), with 15 mcg of fentanyl was injected into the subarachnoidal space. Adequate analgesia was not reached for approximately 45 min, at which time she developed a dense sensory level of anesthesia to the T12 level. Once this level was obtained, the remainder of the procedure was uneventful. Postoperativly, the patient was comfortable, and she returned to full alert status after one and half hours. At the end of the surgery, she had BP 126/78, HR 91, RR 18, Temperature 37.0°C, SaO2100%. Laboratory results showed PT 10.8, INR 1.1, albumin 3.3, Na 138. She received 1.5 L of crystalloids and estimated blood loss was 100 ml, urine output 200 ml. She also received 1 unit of blood and 250 mL of red blood cells (RBC).
As a consequence of the increasing life expectancy in the USA, elderly health issues and age-related diseases have become more prevalent. With more technologically advanced health care, more elderly patients are able to proceed with complex operations. However, the incidence of anesthetic and surgical complications are predictably increased due to their senescent changes. The incidence of postoperative respiratory, cardiac, and renal complications were significantly increased in 404 patients over 80 years of age.[
Although the differences in mortality rates between general and regional anesthesia remains unclear,[
In regional anesthesia, age is well-described as one of the factors that influences effective analgesia onset and duration. Aging has an impact on pharmacokinetics and pharmacodynamics. One prospective double-blind study reported an almost 50% decrease in minimum effective local anesthetic volume required for brachial plexus block in patients older than 65 years.[
There are numerous factors affecting the achievement of successful spinal anesthesia including baricity of anesthetic solutions, position of the patient during and immediately following injection, drug dosage, barbotage, and site of the injection. Other minor factors include the age of the patient, CSF fluid, curvature of the spine, drug volume, intraabdominal pressure, needle direction, and patient height.[
The ultimate sensorimotor block follwoing subarachnoid anesthesia essesntially requires a reduced dose of local anesthetics (hence, local anesthetic toxicity is rarely a concern) and is often more complete when compared with an epidural block. With higher cephalad spread of local anesthetics in the elderly,[
Increasing age is associated with a reduction in peripheral nerve function, production of myelin sheath protein, and subsequently nerve conduction velocity.[
Additionally, the recognized side effects following spinal block, including, hypotension should be more considered in the elderly. Age-associated autonomic nervous system changes and decreased baroreceptor sensitivity due to chronic high blood pressure may worsen hemodynamic changes after blockade. More elderly patients with oxygen desaturation were reported following spinal anesthesia.[
A delayed spread and onset of action of local anesthetics following subarachnoid blockade in extremely elderly patients can be expected, and may be secondary to various anatomical and physiological causes. As shown in this case report, up to 45 min may be required for the anesthetic effect to occur. Patience and expected delays for the onset of sensory-motor block after a subarachnoid blockade is suggested, prior to converting to general anesthesia.
