Ford et al (6) reported a lack of accuracy with noninsulated needles once the needle tip passed the target nerve Ford et al suggested the use of nerve stimulators with a constant current source, based on the comparison of the electrical characteristics of peripheral nerve stimulators. The use of nerve stimulation became commonplace in clinical practice only in the mid- to late 1. Research on the needle- nerve relationship and the effect of stimulus duration ensued.
More recently, the principles of electrical nerve stimulation were applied to surface mapping of peripheral nerves using percutaneous electrode guidance (PEG) (1. This chapter discusses the electrophysiology of nerve stimulation, electrical nerve stimulators, various modes of localization of peripheral nerves, and integration of the technology into the realm of modern regional anesthesia. What is Peripheral Electrical Nerve Stimulation?
Nerve stimulation is a commonly used method for localizing nerves before the injection of local anesthetic. Electrical nerve stimulation in regional anesthesia is a method of using a low- intensity (up to 5 m. A) and short- duration (0. Hz repetition rate) to obtain a defined response (muscle twitch or sensation) to locate a peripheral nerve or nerve plexus with an (insulated) needle. The goal is to inject a certain amount of local anesthetic in close proximity to the nerve to block nerve conduction and provide a sensory and motor block for surgery and/or, eventually, analgesia for pain management. The use of nerve stimulation can also help to avoid an intraneural intrafascicular injection and, consequently, nerve injury. Electrical nerve stimulation can be used for a single- injection technique, as well as for guidance during the insertion of continuous nerve block catheters.
More recently, ultrasound (US) guidance and, in particular, the so- called dual guidance technique in which both techniques (peripheral nerve stimulation . The goal of nerve stimulation is to place the tip of the needle (more specifically, its orifice for injection) in close proximity to the target nerve to inject the local anesthetic in the vicinity of the nerve. The motor response (twitch) to PNS is objective and reliable and independent from the patient's (subjective) response. Nerve stimulation is often helpful to confirm that the structure imaged with ultrasound (US) is actually the nerve that is sought. This is because the needle- nerve relationship may not always be visualized on US; an unexpected motor response can occur, alerting the operator that the needle tip is already in close proximity to the nerve. Likewise, the occurrence of a motor response at a current intensity of. The disadvantages of PNS are the need for additional equipment (nerve stimulator and insulated needles), the greater cost of insulated needles, and abnormal physiology or anatomy where it may be difficult to elicit a motor response.
PNS is not reliable in a patient receiving muscle relaxants. Basics of Neurophysiology and Electrophysiology. Membrane Potential, Resting Potential, Depolarization, Action Potential, and impulse Propagation. Figure 1: A) Schematic anatomic and electrophysiologic structure of nerve fibers of myelinated and (B) unmyelinated nerve fibers.
All living cells have a membrane potential (a voltage potential across their membrane, measured from the outside to the inside), which varies (depending on the species and the cell type) from about - 6. Nerve and muscle cells in mammals typically have a membrane potential (resting potential) of about - 9. Only nerve and muscle cells have the capability of producing uniform electrical pulses, the so- called action potentials (also called spikes), which are propagated along their membranes, especially along the long extensions of nerve cells (nerve fibers, axons).
A decrease in the electric potential difference (e. V to - 5. V, or depolarization) elicits an action potential. If the depolarization exceeds a certain threshold, an action potential or a series of action potentials is generated by the nerve membrane (also called firing) according to the all- or- nothing rule, resulting in propagation of the action potential along the nerve fiber (axon). To depolarize the nerve membrane from outside the cell (extracellular stimulation), the negative polarity of the electrical stimulus is more effective in removing the positive charge from the outside of the membrane. This in turn decreases the potential across the membrane toward the threshold level. There are several types of nerve fibers.
Each fiber type can be distinguished anatomically by their diameter and degree of myelinization. Myelinization is formed by an insulating layer of Schwann cells wrapped around the nerve fibers. These characteristics largely determine the electrophysiologic behavior of different nerve fibers, that is, the speed of impulse propagation of action potentials and the threshold of excitability.
Most commonly, the distinguishing features are motor fibers (e. C- fibers (which transmit severe, dull pain) have very little to no myelinization and are of smaller diameter. Consequently, the speed of propagation in these fibers is relatively low, and the threshold levels to external stimulation, in general, are higher. There are several other, efferent fibers, which transmit responses from various skin receptors or muscle spindles (Ad). These are thinner than A. Some of these (afferent) sensory fibers, having a relatively low threshold level, transmit the typical tingling sensation associated with a lower level of pain sensation when electrically stimulated.
Such sensation can occur during transcutaneous stimulation before a motor response is elicited. The basic anatomic structure of myelinated A. The relationship between different stimuli and the triggering of the action potential in motor and pain fibers is illustrated in Figures 2. A, B. Threshold Level, Rheobase, Chronaxy.
A certain minimum current intensity is necessary at a given pulse duration to reach the threshold level of excitation. The lowest threshold current (at infinitely long pulse durations) is called rheobase. The pulse duration (pulse width) at double the rheobase current is called chronaxy. Electrical pulses with the duration of the chronaxy are most effective (at relatively low amplitudes) to elicit action potentials.
This is the reason why motor response can be elicited at such short pulse duration (e. Typical chronaxy figures are 5. Figure 3 illustrates the relationship of the rheobase to chronaxy for motor fibers versus pain nerve fibers. Impedance, Impulse Duration, and Constant Current. The electrical circuit is formed by the nerve stimulator, the nerve block needle and its tip, the tissue characteristics of the patient, the skin, the skin electrode (grounding electrode), and the cables connecting all the elements. The resistance of this circuit is not just a simple Ohm's resistor equation because of the specific capacitances of the tissue, the electrocardiogram (ECG) electrode to skin interface, and the needle tip, which influence the overall resistance. The capacitance in the described circuit varies with the frequency content of the stimulation current, and it is called impedance, or a so- called complex resistance, which depends on the frequency content of the stimulus.
In general, the shorter the impulse, the higher its frequency content, and, consequently, the lower the impedance of a circuit with a given capacitance. Conversely, a longer pulse duration has a lower frequency content. As an example, for a 0. Hz plus its harmonics; whereas for a 1. In reality, the impedance of the needle tip and the electrode to skin impedance have the highest impact. The impedance of the needle tip largely depends on the geometry and insulation (conductive area).
The electrode to skin impedance can vary considerably between individuals (e. Because of the variable impedance in the circuit, created primarily by the needle tip and electrode to skin interface, a nerve stimulator with a constant current source and sufficient (voltage) output power is important to use to compensate for the wide range of impedances encountered clinically.(A) Action potential, threshold level, and stimulus.
